In the March issue of the TW eTECHreport Fitting Points for the Advanced PlayerIt’s pretty safe to say that many clubmakers who have been involved in serious clubfitting for a number of years have begun to realize this common sense fact – the actual level of game improvement and score improvement from custom fitting is very often directly proportional to the golfer’s handicap.

When we talk about improving accuracy in Common Sense Clubfitting, the emphasis is on making changes to the golfer’s clubs which result in the clubface being aligned in a manner relative to the golfer’s swing path that starts the ball on a tighter azimuth and/or prevents the axis of backspin from being tilted as much off vertical.

Fitting Points for the Advanced Player It’s pretty safe to say that many clubmakers who have been involved in serious clubfitting for a number of years have begun to realize this common sense fact – the actual level of game improvement and score improvement from custom fitting is very often directly proportional to the golfer’s handicap. In other words, the higher the handicap, the more chance the golfer will walk away from a truly accurate clubfitting with a greater decrease in their handicap and a more visible improvement in their ball striking than the golfer with a lower handicap. Sure, there are always exceptions to any rule, but by and large, it is much easier to bring about a 3, 4, 6, or even 8 shot decrease for a 20 handicap golfer than for a low double digit to single digit handicap player. The reason is of course because the lower the handicap, the more golf athletic ability the player possesses to be able to adapt their swing to whatever is not properly fit in the clubs to their individual size, strength, athletic ability and swing characteristics. Higher handicap golfers make more swing mistakes and typically possess a lower level of golf athletic ability than low handicap players. In most cases, the swing errors of the middle to higher handicap golfer can be offset, reduced or even cured by accurate clubfitting changes. No question, there is a point among golfers where the handicap may be so high and the ball striking skills so poor that clubfitting changes may not have that much of an immediate game improvement effect. But in general, if the golfer has the ability to get the majority of their shots airborne, accurate custom fitting can and will bring about very measurable and visible changes in their ball hitting ability. Not only that, but proper clubfitting for the high handicap player most definitely paves the way to getting a lot more positive and permanent results from swing coaching. So what about the advanced golfer? If proper fitting cannot turn an 8-hdcp into a 4, what can it do and how should the clubmaker approach the goals of a fitting session for the more advanced golfer? For the higher handicap golfer, fitting successes are more often measured in greater distance, better accuracy and better on-center hit consistency. For the advanced player, fitting successes lie more in a change in shot shape (trajectory and ‘shot workability’), shot consistency, as well as in the shaft feel or impact feel. Real score improvement for the advanced player then comes from the effect the fitting changes have on increasing the better player’s confidence, which in turn breeds a more consistent swing. Occasionally you will achieve a dose of success for an advanced player in delivering more distance and/or better accuracy than what their previous, ill-fit clubs could generate, but by and large the advanced player’s fitting success is more a case of quality than quantity. Length No question, the advanced golfer usually has the golf athletic ability to play with longer lengths than the average golfer. In addition, the better player has the swing mechanics that can achieve a higher clubhead speed from a longer club length to gain a little more distance. However, when you realize the average driver length on the PGA Tour has been 44.5” since 2005, and you realize the average length of standard drivers sold off the rack is 45 to 46”, moving the advanced player from a standard length, 45 to 46” driver to one that is a little shorter is a move that can deliver more on center hit consistency as well as more consistent accuracy with typically very little loss in distance. Length in the advanced player’s irons is largely a matter of comfort to be able to maintain a consistent stance, posture and alignment, rather than to go for more clubhead speed with longer lengths. Going longer in the irons than what the wrist-to-floor dimension dictates is never as wise as staying with the W to F length and then potentially looking at changing the iron to iron length increments from the usual half-inch to 3/8”. Loft Advanced golfers are no different in their driver and wood loft fitting than any other golfer. Swing speed + angle of attack + the shaft bend profile effect on launch angle + the nature of the fairway turf for roll after carry on the golf course dictates the best driver loft for the better player just as it does for the less skilled golfer. Fairway wood loft is a matter of finding the lowest loft the golfer can easily hit high to fly off the deck, combined with the determination of whether the lowest loft fairway wood is intended to be played more off the tee on tight par-4/5 holes or as a long second shot club. If the player’s “second longest hitting wood” is for use more off the tee than off the deck, choose the lowest loft the golfer has reasonable confidence in getting well up to fly. If the use is more off the deck than off the tee, then add 1° to the loft of what the advanced player says he/she can hit well up in the air to fly (advanced players can tend to lie to impress you more!!). In other words, make darn sure the player can consistently get that low loft well up to fly from a normal fairway lie. Loft between fairway woods is chiefly a product of the player’s swing speed/distance. Over 95mph, start with 4° loft between the lowest loft wood and the next fairway wood. Under 95mph, suggest a 5° separation in fairway wood lofts to ensure a viable distance separation between the fairway woods. Iron loft for the advanced player is both a product of what set makeup combination of hybrids and conventional irons should comprise the golfer’s full iron set, as well as finding the lofts + shaft effect that will generate the shot shape and distance with which they are most comfortable. From an iron set makeup perspective, some advanced players really can hit and should use a conventional 3-iron vs a similarly loft and length hybrid. However, most advanced players should seriously think about using a 3- and 4-hybrid and then starting the conventional irons with the 5-iron than to keep fighting the macho desire to keep the 3- and 4-irons in the bag. There tend to be a much higher percentage of advanced players with higher swing speeds than average golfers. This allows the advanced player the “luxury” of being able to use more “traditional loft” iron models, i.e. 28° 5-iron, and still be able to generate enough distance per club so they are not at a disadvantage when hitting their approach shots. Most advanced players are more concerned ensuring a very consistent distance increment between irons than trying to gain more distance overall with an iron set. While this is a feature of the TrackMan™ system that few other launch monitors can offer, taking the advanced golfer through a session of hitting each iron to determine the exact carry distance of each can be an incredibly valuable exercise. It is very common to see irons which are perfectly incremented in loft to each other still result in inconsistent distance gaps between irons because of the slight, but consistently different swing positions the golfer achieves at impact with different irons. It is very common when doing such a precise distance gap analysis to end up bending the advanced golfer’s irons in a different series of actual loft changes from iron to iron to be able to end up giving the golfer the same, exact distance difference between Lie What more need be said than to re-verify the fact that the lie angles must be fit in a dynamic form to allow for the variations in shaft droop and golfer impact position for each, individual iron. Whether by sole contact on a lie board or with the Golftek company’s Lie Detector System, each individual club must be dynamically fit for lie to ensure accuracy. And do NOT forget the advanced player’s putter. While the putter only needs to be fit statically for lie, few advanced players ever have this done. Face Angle It is interesting to note that the advanced player’s requirement for woodhead face angle resides more in the LOOK than in the realm of its effect on accuracy. Often a better player will set a driver in the playing position and immediately comment positively or negatively on the visual appearance of the face angle. They do this because it is very common for the better player to have a very discerning eye for whether the head sits open, square or closed, acquired from years of hitting shots with different clubs. No question face angle affects accuracy for the better golfer in the same way it does for the less skilled player. Equally, if the better player has any type of misdirection or usually, “nagging R to L or L to R flight issues”, the face angle is definitely where this can best be resolved or reduced. Wood club accuracy is typically more a case of “tweaking the workability” of the ball for the advanced player than it is significantly reducing a slice or hook. Therefore, fitting the face angle for the better golfer is more a case of letting the golfer look at different driver and woodhead models and having them tell you what they like to look at in terms of the face angle in the playing position. Grip Nine times out of ten, the advanced player is going to tell you what grip model and grip size they desire rather than to let you do the fitting and advisement. This is because most good players, through trial and error, have found the grip size that feels most comfortable. The only problem the clubmaker has is discovering exactly what that size is, and determining how to duplicate it on the new clubs. Many times the grip size the player tells you he/she likes is not really its actual measured size. It is very common for an advanced golfer to detect even the slightest change in the diameter of the grip for BOTH their hands. Therefore, learning to work with calipers, rather than pre-made grip size gauges, to measure and reproduce the upper and lower hand diameters of the grip is going to result in more grip fitting success with the advanced player. And many times because some grip models expand/contract differently when installed, achieving a specific size may require trial and error rather than the advised wraps of tape taught in numerous books on clubfitting and repair. Shaft Ahhhh yes, the shaft and the advanced player. . . . have you got a month?? No question, shaft fitting for the advanced player is a far more challenging task than for the less skilled player. The reason is because, 1) the better player places a lot more psychological emphasis on the importance of the shaft to the point of nausea or extreme nit-pickyness (!!), 2) the better player often depends on the shaft to help achieve the precise shape of the flight of the ball he/she desires, 3) the better player very often has the ability to feel different things in the bending action of the shaft that less skilled players cannot detect. In general, this means you still approach the start of the shaft fitting for the advanced player just like any other player. Swing speed + evaluation of the golfer’s transition, tempo, release and physical golf strength can be used to reduce the possible shaft selections to those which fall into the combined categories the golfer possesses. However, because most good players do depend heavily on the bending feel of the shaft before deciding they like or dislike the shaft, using the TWGT Bend Profile Software to help evaluate the effect of the shafts’ bend profile design on their bending feel can and will be very helpful in fitting the advanced player. If the golfer can tell you shafts he/she has used in the past which have felt good to them, you may be able to find these shafts in the Bend Profile software’s data base. By bringing up the bend profile graph curve of the shafts the player has liked, or disliked, you then have a basis of comparison to be able to know what other shafts happen to display the same or different bend profile characteristics. By comparing the graph lines of liked/disliked shafts to the graphed profiles of other shaft models, it becomes a lot easier to determine how various shafts differ, and from that, to come up with even better shaft recommendation. The bending feel of the shaft can often be the number one most important aspect to shaft fitting for the advanced player. Finding a shaft that delivers a specific, desired trajectory and shot shape. Swingweight/MOI Matching Every golfer needs to be fit for a weight distribution of their clubs that is well matched to the golfer’s strength, swing transition and swing tempo that will allow them to achieve the most consistent rhythm and tempo for a higher level of on center hit, and on plane/swing path consistency. The main difference in fitting the advanced player vs the average golfer for the right swingweight or MOI of their assembled clubs is that typically the advanced player will offer a lot more feedback than will most average golfers to guide the determination of the final weight distribution. To swingweight or to MOI match the advanced player’s clubs is not a matter of performance as much as it is a task of convincing the player MOI matching can be superior to swingweight matching. Better players tend to be more “stuck in their ways” and more hesitant to change. Swingweight matching has been the mainstay of club to club weight distribution matching for over 80 years. MOI matching is relatively new and practiced only by a few hundred Clubmakers in the know. But since MOI matching has been done by these pioneering Clubmakers since 2003, the data to support its superiority to swingweight matching is growing. The experience of the Clubmakers who have embraced MOI Matching as their only method of golf club weight balance matching is showing that the advanced player tends to notice the improvement in on center hit consistency brought by MOI Matching sooner and in some cases, more dramatically than average golfers. All it takes are the brains to learn how to explain the difference between MOI Matching and swingweight matching, and the courage and tenacity to overcome the initial hesitation the player may have to trying something of which he is not aware. Set Makeup No where is there a better chance to fit and build additional clubs for use on different types of golf courses than for the advanced player. Good players in general may tend to play different courses more often, and their awareness of the need for different clubs for different course requirements is greater than that of the average golfer. Therefore, a big part of a fitting for an advanced player should be to ask if he/she plays a lot of different golf courses and explain the need to have different wedges, a different hybrid or different tee shot club for tighter holes. Because there can often be a bit of ego associated with some advanced players, there is a chance the advanced player may experience a case of “set makeup denial”. Roughly translated, this means some advanced players may be resistant to using a higher loft fairway wood or to using more hybrids and fewer conventional irons to enable them to play smarter golf. In the ego of golf, some players feel it is a sign of weakness to have a 4- and 5-hybrid to replace the low lofted conventional 4- and 5-irons – the good clubmaker has to have the patience to convince such players that it is only a sign of stupidity to resist such a game improvement change. _____________________________________________________________________________ 12 Myths Being Spoken in Multiple Languages
In 2007, the 12 Myths booklet made its first departure outside the English language when clubmaker Andre Thaon from LePecq, France translated and printed the booklets in French. Now a year later, Thaon reports that having a French version of 12 Myths has made a huge difference in the promotion of his custom fitting services. Andre tells us, “When I start educating a golfer about proper fitting, if they do not decide immediately, I give them the 12 Myths and then see them coming back a few days later after having decided to take the plunge. I can definitely say that of those golfers that decide to be custom fit, 90% have read the 12 Myth books that we provide. It is my best salesman.” A French 12 Myths is just the beginning. By the time the 2008 golf season is in full swing, 12 Myths will be available in Swedish, German, Dutch and Spanish for golfers in each of those countries to fully understand how professional custom fitting is far better for golfers than buying standard made clubs off the rack. Swedish PGA members Matz Evensson and David Leet have joined forces to translate, print and distribute a Swedish language version of 12 Myths in their home country this year. The two have been active and staunch supporters of professional custom clubfitting for several years, and agree on the importance of presenting the facts of custom fitting to the golfers of Sweden in their own language. As part of a buying group that includes 93 other Swedish PGA members, Matz and David have already made plans to distribute numerous copies of the Swedish 12 Myths to each of the pros who are members of their buying group to use to promote custom fitting to a wide number of Swedish golfers this year. German PGA member Mike McFadden and his son Jason are in the process of completing the translation of 12 Myths into German with plans to complete the printing of the booklets by this Summer. As with Matz and David in Sweden, Mike and Jason have already committed to supplying as many of their fellow German PGA members as possible with copies of “Zwolf Mythen” to promote custom clubfitting to golfers all over Germany. Clubmaker Marcel Bal of Golf Op Maat from Den Helder in the Netherlands has already completed his task of translating and printing the 12 Myths booklets in his Dutch native language. Marcel has made “12 Mythen” available to all of the Custom Clubmakers in Holland and is in the process of working with the Dutch PGA to make the booklets available to all the Dutch pros. And finally, clubmaker Ed Coleman, a recent émigré from his home country of England to the warm, sunny climes of Spain, has completed the translation and printing of the 12 Myths booklet into Spanish. As a result of Ed’s commitment and work, “12 Mitos” is now available to inform Spanish golfers of the real benefits that can be realized through professional custom fitting. As copies of each different version of 12 Myths become available, TWGT will try to maintain a small stock of ______________________________________________________________________________ TWGT Bend Profile Software Update
Included in the upgrade will be tremendous increases in the number of models of shafts from Aldila, UST, Grafalloy, True Temper graphite, True Temper steel, Royal Precision steel, Aerotech, Graphite Design and TWGT. Within these quality makers of shafts, our Bend Profile software should have virtually 100% of each of these companies shaft models and flexes. We’re very grateful the shaft makers agreed to send us multiples of all their shafts, or as many as they could, for us to measure and include in the data base upgrade. This upgrade we’re on the verge of sending out is by no means the end of add ons to the data base for 2008. Cataloging, obtaining and testing shafts is going to be a never ending, ongoing project for our TWGT Bend Profile software. Because we insist on measuring a minimum of 2 pieces of each model and flex to get a sense of consistency, this is a process that takes a lot of time to dispatch with accuracy. But I have always wanted to be able to offer Clubmakers a better way to empirically compare the bend profile design of as many shafts as possible so they can make better and better shaft fitting recommendations for golfers, so we’ll keep working to provide the information. ______________________________________________________________________________ Common Sense Clubfitting for AccuracyBeing able to improve the golfer’s shotmaking accuracy is one of the most important areas of game improvement through clubfitting that Clubmakers and golfers seek. When we talk about improving accuracy in Common Sense Clubfitting, the emphasis is on making changes to the golfer’s clubs which result in the clubface being aligned in a manner relative to the golfer’s swing path that starts the ball on a tighter azimuth and/or prevents the axis of backspin from being tilted as much off vertical. In this month’s TWGT E-TECHreport, we will cover the chief elements of clubfitting related to improving the golfer’s shot accuracy. Key Fitting Specifications for Shotmaking Accuracy Lie Angle Clubmakers are well aware of the importance of lie angle in producing a consistently accurate ball flight when the golfer that starts the ball on the intended target line. How many times have we encountered a set of clubs for which the lie angles have not been properly set for the golfer, only to hear about shots that fly to the left or right of the target? Properly fit lie angles reward the golfer with an accurate ball flight when they make the proper swing motion.
An angled orientation of the ink line on the face means the lie is incorrect for the golfer. When the ink line left on the face from impact with the ball is angled toward the heel of the clubhead, the iron will need to be bent more upright. If the ink line left on the face tilts toward the toe, the iron must be adjusted more flat to fit the golfer. And don’t worry, Sharpie pen ink wipes off the face of any clubhead with a solvent dampened cloth or paper towel! Face Angle (Driver, Fairway Woods and Hybrids) Face angle is the best way to influence the initial direction that the ball will travel after impact. In combination with swingpath, this will determine how much sidespin (axial tilt) is imparted to the ball. If you find that the golfer has a repeating swing path, the goal should be to minimize the spread between the face angle at impact and the swingpath to create less axial tilt, resulting in a straighter flying shot with less curvature. While not everyone has the ability to determine face angle and swingpath by use of diagnostic devices, we can all make some pretty good assumptions based on the ball flight that we observe. In general, a 1 degree change in the face angle will result in a 5 yard direction change at a carry distance of 200 yards. Therefore, in general, a golfer who carries the ball a distance of 200 yards and slices the ball with 30 yards of dispersion flight could expect to see a 15 yard reduction of that dispersion flight by changing to a driver with a face angle that is 3 degrees less open/more closed than the face angle of the driver that produces the 30 yards of slicing ball flight.
Length It’s no secret that the longer the club, the more difficult it is to hit the ball solid and on center a high percentage of the time. Longer length clubs are also more difficult to hit straight because the increased length can alter the swing path and rotational delivery of the face to impact. As Custom Clubmakers, our focus should be on fitting golf clubs for ON COURSE performance. The standard made club companies pushed their standard lengths as long as they have because they are hoping for golfers to hit that “one good shot” that keeps them hunting for more. Distance sells. Unfortunately not nearly as many golfers actually will hit a longer length driver or wood farther as the big companies think. Thousands and thousands of fittings have proven that most golfers will hit the ball farther, straighter and more solid with wood lengths that are shorter than what the standard club companies have made to be their standards for length.
There are additional Common Sense Clubfitting specifications that, when properly fit for some golfers, can work in combination with each other to result in greater accuracy. This will vary from golfer to golfer based on their ability, repeatability of swing motion, and sensitivity to these secondary considerations. In the clubhead itself we can consider offset/face progression, CG location, and the MOI about the shaft axis (how much effort it takes to square the clubface). If a golfer never gets into a proper rotation of the forearms, then these specifications will not have a significant impact on accuracy. In looking at shafts, the shaft weight, torque, and weight distribution/balance point of the shaft can have an effect on the golfers’ ability to consistently deliver the head to impact. Generally speaking, golfers with a faster, more aggressive swing motion and tempo will usually have a greater sensitivity to the weight of the shaft; put a lightweight shaft in their hands and they will can often get very quick with their take away and overall swing tempo. Golfers who exhibit a late and aggressive release of the wrist-cock angle will typically put more stress on the lower part of the shaft just prior to impact. In general these golfers will achieve more consistency with a stiffer overall flex and lower torque measurement shaft. However, small differences in torque differences of less than 2º will not typically exhibit an effect on accuracy of the shot for the same golfer. When it comes to the grip, a component of the club that is too often overlooked, the proper size and texture/tackiness should be determined so the golfer can keep control of the club without excessive grip pressure. The MOI/swingweight and total weight of the clubs as well as the set make up can also contribute to accuracy. As mentioned above, getting the combination of the total weight + weight balance feel of the clubs correct for the golfer is important to accuracy. If we put a club that is too light into the hands of a stronger, more aggressive golfer, they can lose the ability to control the club during the swing, which can result in a higher percentage of off center hits, as well as a more inconsistent swing path and face angle. In addition, if we put a club that is too heavy into the hands of a golfer, it can result in a breakdown of swing fundamentals that will lead to inaccurate shots. The name of the game for scoring in golf is Accuracy. In short, it is much more difficult to make par when the golfer hits the ball in the rough and/or misses greens. If you understand and implement the fitting changes which allow the golfer to achieve even a little higher level of accuracy, lower scores and more enjoyment are soon to follow. _____________________________________________________________________________
TWGT’s Tom Wishon Keynote Speaker for World Scientific Congress of Golf In what is considered a great measure of respect for the man and the custom clubmaking industry, TWGT’s Tom Wishon has been asked to deliver the keynote address for the 5th World Scientific Congress of Golf, to be held March 24-28 in Phoenix, Arizona at the conference center of the San Marcos Golf Resort. Staged every four years, the WSCG is conducted as a serious academic conclave for the formal presentation of original research papers in the fields of The Golfer, The Golf Equipment and The Golf Course. (www.golfscience.us) Wishon has been asked to be the keynote speaker for March 26, the day devoted to the field of golf equipment research at the Congress. As of March 12, WSCG organizers have confirmed an audience of 225, consisting of the heads of engineering and product development for most of the major golf equipment companies, a number of golf magazine and golf media equipment writers/editors, and golf company executives. “I’m truly honored that the WSCG asked me to do the keynote address for their sixth gathering. I was in the audience for the first WSCG in 1990, and I remember coming away from the Congress with the realization there were a whole lot of smart people who participated and presented research papers. I expect with such a group of people in the audience, I will be a little nervous, but I do really look forward to having the chance to share my thoughts on where golf equipment technology is going and where I think it needs to go to ensure an optimistic future for golf equipment companies as well as for the benefit of all golfers who love this great game as I do,” Wishon stated. Tom’s presentation is slated to be Wednesday, March 26, from 8 to 9:30AM and will be on the topic of The Past, Present and Future of Golf Equipment Technology. Attendees will hear Tom offer a brief chronicle of the history of technical developments of the golf club and ball before he takes off into a discourse on his concepts of where golf equipment technology is and should be headed for the future. It is anticipated Tom’s keynote presentation will be video taped to be available through the WSCG’s web site at some point in the future. ______________________________________________________________________________ TWGT New Designs in Stock Finally! Thanks to a very last minute glitch with the shipping company, we delivered the new TWGT designs a little later than we had said in the last E-TECHreport. We should have known about the time we printed a date, Murphy’s Law would pop up and ensure a last minute delay. As a result, Clubmakers who booked advance orders for our new PCF Micro Tour and Micro Wide Sole wedges, the new 919THI fairway woods and the iron looking 585HI hybrid irons, either have just received or will very shortly be taking a look and building the latest members of TWGT’s original clubhead design family.The 705w2 irons are not far behind, due to us around mid April.
