OK ... wow. Just "upgraded" from a 983k to this 905r. Lets put it this way, I signed up for this website just to write a review on this driver.
My 983k was great, but when got this big boy, "with the Speeder Shaft" I was kind of shocked.
Bottom line: I fade the ball. Some may even call it a slice. This thing goes freakin straight. And long...way long. I think it's the way it's weighted. Who knows. What I do know is that I BOMB THIS THING.
