I tried a buddy 905R and loved it after hitting 5 long straight drives. Now I own several with different shafts. My favorite shaft is the Fujikura Speeder 757 but the UST ProForce V2 75 is great also.
I'm willing to give up a few yards for its great feel and sounds vs others.
This driver is the best driver ever made by Titleist. It has a very solid sound and a good look at approach.
