I have a 9.5 910 D3 with Project X Tour Issue 7C3 (6.0). I am looking to lower my ball flight and spin rate. Looking to upgrade to a Proforce. How would the Proforce V2 66 X flex or 76 X flex compare?
It's ALWAYS best to get properly fit for your clubs.
The shafts that you mentioned are going to be pretty similar to the Project X you have. The R.I.P. a 70 is a good shaft, as well as the Motore Speeder VC 7.2.
Do you have any certified Titleist fitters near you?
