Representation
If you picture a set of triangles and compare
one at 56 and one at 57 degrees,
one at 64 and one at 65 degrees,
The length differential between the 56 & 57 degree angles are greater than the length differential between the 64 & 65 degree angles. Herein lays the proof that any static number like ½ inch or ¼ inch variation per club is not mathematically sound. Each increment has to be progressively less than the last increment as the clubs get shorter.
True Length Technology ™ clubs do vary in length. Just in less than the traditional ½ inch increment. In fact the length variance is perfect from club to club, giving one very athletic and repeatable setup position and posture for your personal setup.
As all custom club fitters know, one size does not fit all. Matter of fact, only one size fits you and you alone. As all custom club builders know, length and lie are imperative, but almost all builders only have access to a few charts that are ‘recommended build sizes’ - 2 charts for men, 1 chart for women.
If you look at some of the old ‘Club fitters Rulers’, a single ‘recommended length of golf club’ fit over 3 ½ inches of Wrist to Floor (WTF) variations, except if you were a women, then your clubs would simply be 1 inch shorter. How much sense does that make? Someone with a 34 inch Wrist To Floor measurement is playing the same lengths as someone with a 37 inch Wrist To Floor measurement. This again is not mathematically sound.

Current True Length Technology ™ Status
The True Length Technology ™ system has charts that vary from a Series 0 to a Series 12. Every chart is a Math Model of perfect proportions for each individual series. The math behind the True Length Technology ™ build charts is the answer to your personal athletic address position. Not everyone addresses the ball in the same manner and therefore the target build chart is still susceptible to variation. Wrist To Floor measurements are used but only as a starting point within the fitting process. A full dynamic fitting is still recommended using the True Length Technology ™ Fitting System. We will through dynamic testing with various club lengths during the fitting process find the correct series target length test club using impact labels for center hit consistency and build your custom clubs to the appropriate Series chart for that test club.
Hitting balls allows the fitter to be aware of swing tendencies and club head paths that do influence ball flight. Individual swings certainly do play an active role in determining the correct final lengths and lies. Dynamic fitting is still a necessary step due to different bend profiles of shafts, and the dynamics of the individual’s swing. The math model would remain intact if all lies within the set were altered to the same degree, resulting in an averaging out of today’s swing flaws.
The traditional lie board adjustment will be used for every club once they are built to insure we have the exact lies needed for you.
The golfer who sets up with the traditional stance will often find that the Wrist To Floor measurement will often correlate to the Initial Target Series Chart and will indeed be very close to the final build specification.
Single axis golfers and some women who carry their arms out and away from their body will in all likelihood need a set of greater length and possibly an alternative lie, deviating from what their WTF target indicated. Again, True Length Technology ™ is not a WTF system and traditional fitting procedures will insure a sound fitting to the individual.
People with disabilities, that cannot get into that traditional position may need a variation in length and lie, but will end up in their best athletic position - common to every club.
All of the above scenarios will be addressed during your fitting to determining the proper ‘actual’ build size will be. Once the Target Series Build Chart has been determined, we will build to the specifics of that Target Series chart keeping the math model intact.
Fitting System
Each True Length Technology ™ fitting set has its lengths correlated with its lies - set to a perfect math model for all Series Build Charts. The golfer gets to actually swing a a series of fitting clubs to determine their math profile. When the correct Series is in your hands you will instantly know you have found your specifications for length, and a great indication of lie.
The most satisfying feeling is, when the correct length and lie are determined, you are confident that the entire set will fit like never before. |
