I'm very satisfied with the performance of my 915 3 wood with a Diamana Blue Regular 60g shaft. Now I want to use this type of shaft for my driver, which currently has a stiff shaft and has a 251 cpm (my target driver cpm is 240).
For testing purposes, can i extend the shaft from 43" to 45" and test this on my driver just to make sure it performs well before buying a new shaft for my 915 D3? Thanks.
