spine aligning is a futile pursuit.....

the club lags and leads and droops and "toe ups" in 3 dimensions during the swing.....no amount of club building know how can give you more shaft stability with respect to the shaft's spine because of this continued bending and rebounding....

Dan Stone, titleist vice president of r&d, confirmed this yesterday during a webcast and basically backed up what sasho mackenzie has reported in his shaft papers

but if it feels good.....keep doing it

Technically speaking, an infinitely stiff shaft would be stable. I don't think it would help your game much though :)

Ouch... especially from someone listening to a vp of the parent company who claims to have a driver with 9 sweet spots across the face. :rolleyes::D

The only spined shaft I have ever had broke in half during my downswing on the 15th tee in my first round with it. But hey.... If it feels good, do it!

I'm a little lost with the Mizuno deal, but working a Dennis Deyoung song reference in a shaft spine topic is pretty good. :)

What about the FLO of the shaft? Flat Line Oscillation - The shaft vibrates back and forth in a flat line, as opposed to wobbling out of the line. From someone who has tested a lot of clubs since I had a club repair business you would be shocked on how many clubs would wobble all over the place. Flat Line Oscillation (FLO) finds the real spine. Check out Dave Tutelman's article on this

So Brian was the other guy to do that.

Does NOT puring a shaft also offer a money back guarantee? I think not. :eek:

If you go by what Mike says then it means the shaft broke because it had a defect not because it was spine aligned as spine aligning is futile and won't change the shafts deflection profile. Could have broke in it's normal orientation as you only used it in one round, either that or you need to throttle back....lol.

Broken shaft

Phil,
Just curious, but did the shaft that broke employ naontechnology? Hope you are doing great and beating up more golf shafts!;)

I don't think too many people doubt the shaft is moving all over the place in 3D, but does that really mean that you can't influence or gain superior results by having the shaft oriented a certain way? Having the spine fight or assist a certain bending would seem to be possible.

Using the above Shaftlab graph, perhaps there would be some benefit to tone down the deflection where the 80 and 100 ms marks are. In what way did Stone or MacKenzie say there was no possible benefit? Maybe just too hard to predict ahead of time?
