We talked to our Tour Rep and the 'guestimate' was about 30% will play the driver shorter and the most popular length was 44.5"

Jim McClean actually recommends 44.5" for most golfers. 

A lot of the pro's even take a shorter length by gripping down a bit with the driver to get even more control. I think AK does this on most of the clubs in his bag ?

I use an Aldila NV 55 Shaft stiff flex it is about 46"+ would cutting it to 45" make is stiffer?

I have a 910D2, 10.5*, with an Aldila NV 55 stiff flex, 46.25" if I cut this to 45" wouldnt this make it stiffer?

Cathi my name is Dan W. 

My concern is with the shaft in my club? I looked on the chart but the shaft in my new driver wasn't on list.

The shaft in my new club say's ACCRA.  M3 s2-65 DYMATCH . I have registered my new club but I realize  Titlest is not 

Responsible for counterfeit products ? Any information you can give me would be great! Also am I correct to believe that 

The S-2 indicates my shaft is a double stiff shaft?  

Thanks Dan W.

Your height plays a significant role.
