Michael   The two shafts with the same frequency will have exactly the same timing between full deflection (irregardless of amount of deflection) and getting back to straight. The flex pattern or flex point might cause a difference in feel but if the shaft dose not get back to straight it will n

Michael   Frequency is frequency independent of the shaft. If a certain frequency matches the timing of your swing why would the shaft frequency change unless you changed your timing. You can change your timing buy changing the length of your swing and a few other things but it is not the easiest

Just arrived back in Florida. In most cases I have found that in the case of flat liners all clubs are on the same frequency. There are no fixed rules, I have found a few players where the woods are on a separate line both sloped and flat but with no standard rule. I am not sure you can group all

Doug   I find 10 to 15% of the players I fit are flat liners. There was a time when I thought every one should be. Being a flat liner has nothing to do with tempo. The main reason that people are flat liners is that they take every club back the same distance rather then taking each club back dif

He probably has the wrong frequency shaft. I recently had a long drive guy who was breaking shafts until I fitted him into a softer shaft that matched his timing and he did not break any more shafts. llhack > [Original Message] > From: <[EMAIL PROTECTED]> > To: <[EMAIL PROTECTED]> > Date: 7/24/0

The diameter of the shaft was reduced  by approximately 7% which would reduce the frequency since the moment of inertia is dependent on the square of the materials distance from the center of the shaft. The paint is probably an epoxy. However reducing the mass alone would increase the freque
