Swing Type Plays a Huge Role in Club Fitting

I feel like the quick answer to this question has to start by saying. . . . DUH!! Clubfitting is and always will be about tailoring the specifications of each golf club so they best match the various swing characteristics of each different golfer.
Next time you head to the driving range when most of the hitting stations are in use, stop and look at the differences in how all the different golfers swing at the ball. Inside-out/square/outside-in swing path – fast/medium/slow swing speed – hitting down/swinging level/hitting up on the ball – forceful, aggressive to average to smooth, slower swing tempo – slice/straight/hook the ball – push/straight/pull the ball – early/midway and late release . . . And on and on.
The vast differences in how golfers swing at the ball all translate into a requirement for different Clubfitting specifications for the golfers. This is precisely why the golf industry’s typical business model to build their golf clubs to one series of standard specifications for most of the fitting specifications is so utterly flawed. It is why so many golfers buy golf clubs off the rack and never achieve all they can be as a golfer.
Now don’t get me wrong. Proper fitting is not likely to put you or me on the first tee of nest year’s US Open. But it darn well can make the difference in whether a golfer plays to the best of his/her ability as well as how quickly a golfer can adapt to swing changes when they take lessons. Improperly fit clubs do get in the way of golfers being able to play their best. And not just a little.
Let me tell you a few of the relationships between specific swing characteristics and proper fitting specifications:
Clubhead Speed
The clubhead speed is a critical part of shaft flex fitting. It is also an important element in determining what spacing of club lofts will deliver what amount of distance difference between clubs. Clubhead speed also affects the amount of backspin any golfer will achieve with any clubhead or shaft design.
Downswing Transition Force and Downswing Tempo
Golfers differ in how aggressively they start the downswing from very sudden/abrupt/forceful to very smooth/passive/gradual and all places in between. They also vary in their swing tempo from smooth/rhythmic to aggressive and in between. Downswing Transition force and the Tempo are major factors in choosing the right length, shaft weight, total weight, swingweight, shaft flex, shaft torque.
Point of Wrist-Cock Release
Golfers differ in when they start to unhinge the wrist cock angle from immediately after the downswing starts (early) to very late in the downswing (late) to also many different positions in between. The point of release is a big factor in choosing the right length, shaft flex, shaft bend profile, loft.
Swing Path
Again, you see golfers with swing path variations from very outside-in to square to very inside-out and paths in between. The swing path is a critical factor in determining the golfer’s best lengths and face angle for the woods and hybrids.
Angle of Attack
Whether the golfer swings downward, level or upward to the ball, the Angle of Attack is a key swing element in determining the best loft, best clubhead center of gravity design and clubhead sole design as well.
So the next time you encounter a golfer who thinks he or she is not good enough to benefit from custom fitting, clue them into the fact that the more differences they have in their swing characteristics, the more fitting can step up to help them play better golf.

Tip Soft Shaft: What Does it Mean for Your Swing?

What is meant by a “tip soft” shaft?  A shaft can be designed with any variation in its stiffness over its whole length.  So a tip soft shaft is one that is designed to be more flexible in the tip area of the shaft.  Likewise there can be any number of variations in how stiff the tip section of a shaft is designed.  The reason this is done is to help golfers with different swing characteristics find the right shaft that matches best to how they swing.
Most typically, golfers who unhinge the wrist cock early in the downswing are better fit with tip soft shafts, while golfers who hold that wrist cock until very late in the downswing are better fit with a tip stiff or tip firm shaft.  Those who unhinge the wrist cock somewhere in between early and late then are typically better fit to shafts that are more what is called a tip medium design.
But these terms “tip soft/tip firm/tip medium” are completely generic in their description and in no way tell you HOW TIP SOFT or HOW TIP FIRM is the shaft exactly.  That’s why we created this Bend Profile Software so that clubmakers can see exactly how much stiffer one shaft is than another, and where on the shaft from butt to center to tip is the shaft more or less stiff.
Let me explain using a graph and data from our Bend Profile Software data base.  In this software we store the FULL LENGTH STIFFNESS measurements of over 2,600 different shaft models and flexes so that clubmakers can empirically compare the stiffness design of one shaft to another to help them make better shaft fitting recommendations for the golfers they fit.

Shaft Profiling




These are two different shafts which are designed to be virtually the same exact stiffness from the butt to the center of the shaft, but then different in stiffness for their tip section. In the graph and data box, the 41 to 11 columns tell you WHERE the stiffness measurements were made on each shaft, in inches up from the tip end. So the 41/36 measurements are considered the BUTT end of the shaft, the 31/26 measurements the CENTER section of the shaft and the 21/16/11 considered the TIP Section of the shaft. In the measurements, the higher the number, the stiffer the shaft is at that point.
So from this you can see that the Gold Tour R shaft is more tip stiff than is the Gold Plus High R because the 21/16/11 measurements of the tip section of the Gold Tour are higher and thus more stiff than the same location measurements of the Gold Plus High shaft.
The best way to be sure you are properly fit for the right shafts that match all your swing characteristics is to find a GOOD Clubmaker/clubfitter in your area and have them use their knowledge and experience to custom fit you.

Golf Shaft Fitting: How Does ‘Transition’ Affect Shaft Selection?

Occasionally, we receive questions about golf shaft fitting, so we will do our best to answer them.  Here is a question regarding ‘transition:’  What role does ‘transition’ play on the golf shaft and what kind of tips can you provide in finding the right shaft?
Because the difference in how forceful the golfer starts the downswing can be of high importance to finding the right overall stiffness in the shaft along with the right shaft weight and right headweight feel as well.
Typically if you have two golfers with the same clubhead speed, the one with a much more forceful transition move will do better with at least ½ flex stiffer shaft than what would be normal for that swing speed, with a 20g heavier shaft weight and in the area of 2 to 3 swingweight points higher in the headweight feel than the golfer with a pause at the top and a very smooth, gradual transition move.
Golfers with a strong transition who end up with too light of a total weight and/or too light of a swingweight tend to experience a higher degree of off center hits, more heel side hits, and even the tendency to make a slight outside in path become more outside in.
