I was hitting the 975J (360cc) and I could not make the jump to the watermelon sized 460cc. I favore Titleist drivers because the feedback is so consistent. As soon as you hit the ball, you know where you caught it and where it's going. The 905T did not disappoint. Still true and has a sweet sound, not that hideous ping, like an aluminum baseball bat.
I will probably always stay with Titleist drivers as long as they don't do anything stupid with the design. Buy them 102 years after release and save 50% ($200)
