I bought one. Sorry, I can't definatively answer your question, but mine is quite a bit smaller (400 ccs) and sets up WAY open (not sure if they all do). I would say at least 2*. Great for me, maybe not for others. I've had a number of tour issue drivers and I've never seen anything this open. Very nice clubs that are going on the cheap. I bought one with a pro-launch and it's a nice combo. Seems to play to loft too and, although I've never owned a 460, it's not too awfully loud.
