Shaft Swing Speed Ratings – Why the Range and How to Use Them in Fitting

One of the most helpful points in a shaft fitting is the common use of swing speed ratings for the many different shaft models and flexes which are available to Clubmakers today. In a golf industry consisting of literally thousands of different shafts, the swing speed rating (if accurate) is the first means of narrowing the selection process. [continues below]

Shot Trajectory – What You Can and Cannot Control Through Fitting

Claims for different clubhead and shaft designs to create a visible change in shot trajectory are well known. . . "lower center of gravity to hit the ball higher", "tip flexible bend profile to hit the ball higher," "more rear Cg location to result in a higher trajectory," are all examples of claims made on behalf of specific head and shaft models to allow golfers to change the height of their shots.[continues below]

The Fitting Session in a "Nutshell"

Over the past few years, a number of Clubmakers have asked me how I personally conduct a fitting session. After this many years in the business of custom clubmaking and product design, when I hear this question I usually smile and respond, "with my eyes and my brain!"[continues below]

New wishongolf.com Web Site Coming Soon!

In case you’re not aware, TWGT hosts two very different web sites. www.wishongolf.com is the web site we have created for custom Clubmakers, what we call our "trade web site." This is where our e-commerce shopping site is located with information is more tailored for the Clubmakers. We created www.twgolftech.com as the "pro-custom fitting" web site for consumer golfers, non-clubmakers who need to know why seeing you to be custom fit will ensure a much better playing set than buying their clubs in standard form, off the rack.[continues below]

The Search Continues

Early reports from the major bookstore chains and web site booksellers are saying that golfing readers are buying the latest release in the Search saga, The Search for the Perfect Driver. The follow up to the best selling and award winning Search for the Perfect Club, Search Driver is devoted to educating golfers about their custom fitting needs with the ego club in their bag, the Driver.

Shaft Swing Speed Ratings – Why the Range and How to Use Them in Fitting

One of the most helpful points in a shaft fitting is the common use of swing speed ratings for the many different shaft models and flexes which are available to Clubmakers today. In a golf industry consisting of literally thousands of different shafts, the swing speed rating (if accurate) is the first means of narrowing the selection process.

Ever since swing speed ratings were first introduced to the golf industry in the 1991 book, The Modern Guide to Shaft Fitting, Clubmakers will note that the swing speed rating for shafts is most typically offered in a 10mph range, while sometimes in a 15mph range, for each flex within each shaft model. Why the 10-15mph range in swing speed for shafts?

Primarily, when a swing speed rating is established for a shaft, basic assumptions are made that the golfer with a swing speed within the range will generate the primary bending force on the shaft at the beginning of the downswing to match well with the stiffness design of the shaft. Of course there are exceptions between golfers with the same swing speed in their ability to exert a typical bending force on a shaft. This is one of the reasons that shaft swing speed ratings are most typically created in a 10mph swing speed range.

Following are the basic rules of thumb when comparing the golfer’s swing speed to the swing speed range of shafts for initial selection:

  1. If the golfer has a strong transition move to start the downswing, choose shafts for which the golfer’s swing speed is at the LOWER end of the swing speed range. For example, if the golfer has a driver swing speed of 90mph and has a strong, forceful transition move to start the downswing, the golfer actually needs a little stiffer shaft than what the swing speed indicates. Therefore looking among the shafts that are rated 90-100mph will ensure the shaft is a little more stiff and can thus match better with the greater initial bending force a strong transition move exerts on the shaft.
  2. If the golfer has a smooth or much less forceful transition move to start the downswing, choose shafts for which the golfer’s swing speed is at the HIGHER end of the swing speed range. For example, if the golfer has a driver swing speed of 90mph and has a smooth, easy and gradual transition move to start the downswing, the golfer actually needs a little more flexible shaft than what the swing speed indicates. Therefore looking among the shafts that are rated 80-90mph will ensure the shaft is a little more flexible and can thus match better with the greater initial bending force a strong transition move exerts on the shaft.
  3. If the golfer is "in between" smooth and forceful to start the downswing transition, it is best to choose shafts for which the golfer’s swing speed lies in the middle of the range.

Shot Trajectory – What You Can and Cannot Control Through Fitting

Claims for different clubhead and shaft designs to create a visible change in shot trajectory are well known. . . "lower center of gravity to hit the ball higher", "tip flexible bend profile to hit the ball higher," "more rear Cg location to result in a higher trajectory," are all examples of claims made on behalf of specific head and shaft models to allow golfers to change the height of their shots.

More than any golf club design feature, the golf swing is the chief determinant of how high or low any golfer hits the ball through the differences from one golfer to the next in their angle of attack. If the golfer has an upward angle of attack through impact, the result will be a higher than normal flight. Conversely if the clubhead is traveling on a downward angle of attack to the ball, the player’s shot trajectory will be lower than average.

What causes an upward or downward angle of attack in the swing?

Of all the golf club specifications, clubhead loft is the number one factor that can change the trajectory of the shot. Decreasing the loft for a golfer with an upward angle of attack will visibly lower the height of the shot, while increasing the loft for a golfer with a downward angle of attack will increase shot trajectory. However, it is not that uncommon for a golfer to have such an extreme upward angle of attack that a major decrease in loft will not have an appreciable effect on the height of the shot. This is most commonly seen in golfers who unhinge the wrist-cock angle early to midway in the downswing and allow the clubhead to pass the hands at impact, resulting in an impact position with the wrists flexed forward.

Angle of Attack

If you are fitting a golfer who complains of hitting the ball too high, or if you fit with a launch monitor/TWGT launch mat and see the launch angle is >3° higher than the loft of the driver used to hit the shot, it’s wise to suspect that a case of "wrists flexing forward" at impact is the reason for the high shots. Unfortunately, when the clubhead is traveling this much upward at the moment of impact, there is not a lot that can be done to markedly lower the ball flight other than a series of lessons to address the poor impact position with the hands. Yes, there is no question a significant decrease in the driver loft is the only remedy for such a high shot problem, but given the fact that drivers with less than 8° loft are pretty rare, the amount of help a lower loft can offer to a golfer like this is limited.

Trajectory affecting factors such as vertical Center of Gravity position in the clubhead and tip firm/tip flexible shaft designs are only going to offer subtle changes in the height of the shot, and typically only for golfers with better than average swing fundamentals. One exception to this that we are looking forward to studying in much greater depth is the high trajectory flight of TWGT’s model 770CFE irons. There is no question the 770s do hit the ball visibly higher for any given loft than any other iron model in our design line. If you have a golfer who definitely needs to hit the irons higher to benefit his game, the 770s will perform in that manner.

But the bottom line is that when you encounter a golfer who hits the ball too high, take a look at the golfer’s swing to determine if the reason is related to an early release and a flexing forward of the wrists before impact. If this is the cause, a loft change may help slightly, but you do need to make the golfer aware that significant improvement in lowering the flight of the ball is not likely to happen until they work on their impact position.

 

The Fitting Session in a Nutshell

Over the past few years, a number of Clubmakers have asked me how I personally conduct a fitting session. After this many years in the business of custom clubmaking and product design, when I hear this question I usually smile and respond, "with my eyes and my brain!"

Common Sense Clubfitting Book

Thanks to the success of the book, The Search for the Perfect Golf Club, TWGT was contacted by the producers of the ‘Golf Today’ show for Fox Sports Midwest for the purpose of shooting a 30 minute segment on TWGT and custom fitting. The Golf Today film crew flew to Durango the week of October 16-20 to shoot the show on the scenic Dalton Ranch GC layout as well as in TWGT’s new R & D facility, located on the driving range at Dalton Ranch.

All kidding aside, the fitting session is an event that quite often will be different with different Clubmakers. In my opinion, one can approach the fitting session with the thought to directly address the game improvement needs of the golfer, or to go into the fitting with the idea that you don’t really need to know the specific areas of improvement if you elect to analyze the golfer and simply offer a recommendation for the best overall specifications that match to the golfer’s size, strength, athletic ability and swing characteristics.

If you choose to find which of the game improvement areas outlined in the book, Common Sense Clubfitting, of more distance, better accuracy, more consistency, the right trajectory and the best feel that the golfer wishes to achieve, it is always easy to consult the poster that comes with each copy of the book to look for the "A" Effect specifications which will address the desired game improvement area.

On the other hand, there is nothing wrong with simply taking the approach to fit the golfer to the custom specifications which will bring about the best of all five of the game improvement factors. Unless the golfer specifically tells me there is one game improvement area he/she wishes to singly address, I tend to take the other approach and shoot for the fitting recommendations that will work on all five of the game improvement factors.

In a nutshell, here is how I perform a fitting session for a golfer.

1. Ask the player to fill out the fitting questionnaire I have created (see pdf file). Because this is an extensive form with a lot of questions, it may be advisable to let the golfer have a day or more to take the time to sit down and complete the entries.

2. Next I check a few of the specifications of the golfer’s current set. . .

A. Set makeup
B. Driver loft, length, face angle, swingweight, total weight
C. 5 or 6-iron loft, length, face angle, swingweight, total weight
D. All wedges’ loft, sole angle, sole width, swingweight, length

Note: I do not need to measure the lie angles because I will dynamically fit the lie of the irons and statically fit the lie of the wedges and putter exactly to the golfer.

3. Obtain the following measurements from the golfer. . .

A. Swing speed with the driver or 3-wood and the 5 or 6-iron, whichever the golfer is more comfortable in hitting

B. Wrist to Floor dimension

C. Hand and Finger measurements (as described in Common Sense Clubfitting book)

4. Either while the golfer is hitting shots for me to obtain the swing speeds, or from separate swings, I observe and analyze the golfer’s swing for the following characteristics:

A. Swing plane – flat, normal or upright
B. Swing path – outside/in, inside/out or square
C. Transition – forceful, average or smooth and easy
D. Tempo – quick, average or slow
E. Release – early, midway or late
F. Launch Angle or Trajectory – I have a launch monitor. Many Clubmakers do not. If you do, have the golfer hit shots with a driver of KNOWN LOFT, chart the point of impact on the face with impact labels, and note the most consistent or typical launch angle. Mentally calculate the angle of attack by comparing the launch angle to the driver loft. If you do not have a launch monitor then shame on you then for not using our TWGT Launch Mat to obtain the launch angle. For less than $100, it will accurately indicate the golfer’s launch angle with any club. If you don’t have a launch monitor or our Launch mat, you have to watch the golfer’s trajectory and judge if the flight is higher than average, about average or lower than average compared to your experience in seeing a lot of golfers hit shots.

5. Consult the responses in the fitting information form the golfer filled out and start thinking of "symptom vs prescription" relationships between specific problem areas and "A" effect fitting changes as described on the chart that comes with the Common Sense Fitting book.

A. Slicer or Hooker – face angle, length, swingweight/totalweight thinking
B. Wants more Distance – loft, length, swingweight, total weight thinking
C. More Consistency – set makeup, length, swingweight, total weight thinking

Note: I don’t waste time thinking about the trajectory or the feel because when I make all of the fitting recommendations for Distance, Accuracy and Consistency, matters of the right trajectory and best feel for the golfer will be taken care of automatically. Exception? Really good ball strikers or very anal/picky golfers – here I will ask specific questions about the type of feel they like/dislike and then think about the shaft, swingweight, total weight, clubhead model recommendations that may best deliver the specific feel desired.

6. Compile the Fitting Recommendation

A. First comes the FULL set makeup. This is without question, one of the if not THE most powerful of all the fitting recommendations you’ll make. Let me put it this way – if the golfer walks in with a standard OEM set of 1, 3, 5, woods + 3-PW,SW irons and is a double digit handicapper or higher, the effect of the set makeup change alone will make the golfer as pleased as punch on its own. Err on the side of no 3-wood, more high loft woods or hybrids, fewer conventional irons and the best wedge and putter fitting changes you can offer with the vast majority of the golfers you service and you will be even more of a hero.

B. Driver specifications

C. Fairway Wood Specifications

D. Irons and Hybrid Specifications

E. Wedge Specifications

Conclusion

Almost all the time I will build a test wood and test iron with all the fitting recommendations built in for the golfer to hit for 3-4 ball striking/playing sessions on his/her own. I ask them to note the pluses and minuses from their experience and come back in for a final consultation. At that time I will know if the initial recommendations were right on, or need to be tweaked in any manner. If I have to "eat" a shaft or grip from the test clubs due to a different/better one being identified after the input session, so be it. That’s all part of GOOD service in clubfitting and should easily be covered by the final retail price charged to the golfer for the custom fit/built clubs.

Iron and hybrid lie angles will be dynamically fit when the golfer comes in to pick up the final clubs as the last exercise between me and the golfer in the fitting session.

Grips will have been fit separately from a combination of the hand/finger measurement with input from the golfer during a "here, grip this and tell me if you like it" part of the fitting session.

I spoke about swingweight fitting in this session instead of MOI matching only because I fully realize that so many Clubmakers and golfers are so ingrained with the 80 yrs of swingweight being the industry’s accepted method of club to club swing feel matching. Of course we believe in the swing feel matching superiority of MOI matching all clubs. When that is done as a replacement for swingweight matching, we use the test clubs along with the basic thought process for swingweight recommendation to come up with a starting MOI for the test clubs. During a hitting session with the golfer, we add lead tape to the head and look for impact label feedback as well as golfer feel feedback to determine the final MOI for all the woods and then all the irons.

Next month, I will be happy to share my thinking process for the actual clubhead model recommendation process in a typical fitting.

Last point – All I wanted to do in this discussion was let you know a little bit about how I go through the motions and how much I am processing information against my fitting knowledge and experience to hunt for the right specifications for the golfer. Other Clubmakers may do it differently, that’s fine, but the bottom line is to use the principles of Common Sense Clubmaking which identify what club specs have the biggest effect on building a set which offers the best combination of Distance, Accuracy, Consistency, Trajectory and Feel to each individual golfer.
