I just got a Mizuno Blue Rage 9 degree driver. It is 350cc's and it is wonderful. I went to the range today and hit it pretty solid. I purchased it off ebay for only 37 dollars. I feel like I stole something. I have to ask myself the question how big can drivers really get. I mean I think my clubhead is huge. I can't even imagine trying to swing a 460cc driver. I guess whatever makes you feel comfortable. I am happy to have spent money on this driver it will be the bag for a long time. I must say bye to my Wilson Deep Red 305cc Driver. What a time I had with it.
