I originally asked this question under a discussion on the 913 D3 Driver, but thought perhaps it deserved it's own space...
I currently have a set of AP1's with Titleist 65i (stiff) shafts. I am seriously looking at picking up a 913 D3 driver for this years season.
I am curious whether the shafts I use in my irons provide some guidance on which shaft I should look at for the D3, or if the science in the swing between the irons and the driver is so different that one cannot draw that type of conclusion.
My current driver is a stock shaft in one of the competitors clubs (also a stiff shaft).
