I have a Project X Tour Issue 7D3 (5.5. Frequency) in my 910d and love it. Since the 8D4 (5.5) is not offered by Titleist, I am thinking of soft stepping the 8C4 for my 910F 3 wood to make it play a little less stiff.
Do you have you any data or experience with this that you may share?
Thank you,
Dave
