I bought a used Titleist 910 D2 that had a R flex MFT Diamana ka'ali in it at stock length. Didn't mind the R flex because my plan was to put a Fuji Motore Speeder VC 7.1 stiff in it. (I could buy the entire club for less than I could buy the head only).
I also bought a used Titleist 910 F 15* 3 wood that had a S flex MFT Diamana ka'ali in it at stock length.
Well, the Fuji didn't pan out for the D2 head so just for kicks, I put the 3 wood shaft in the D2. I measured it at 43.75 inches and the swingweight is C6.
After 2 range sessions, I am seriously considering leaving it alone like it is. Unbelievable how I lost no distance compared to the Fuji, but I hit it square in the center and straight. The most interesting aspect I noticed is the boring, penetrating flight with what appears to be a lot of rollout. I also tee the top of the ball even with the top of the crown or I catch it too high on the face.
Well, I needed a 3 wood shaft so................. I butt cut the R flex ka'ali down today to 43.5 overall length but haven't hit it yet. When I hit the 3 wood with the driver length shaft in it yesterday at the range though, I hit it well, so trimming it to proper length should not be a problem.
I'm 6 feet tall & golf is a weird game.
