I'm probably late, but will chime in on this. For two days when I caddied in Colorado for the city championship we had a kid in our group from Texas who played golf for CSU. I'm not short at about 6' 2" and I will say that this guy was a pretty big guy - I would say about 6' 4" maybe 6' 5" and pretty stout, but not huge. He had a Cleveland Launcher Comp with a Stulz shaft that he borrowed from a local pro because the airline lost his clubs on the way to the tourney. He swung out of his shoes, literally on every drive. He truly subscribed to "bomb and gouge". He would slip (it was a little damp) he swung so hard. He loved the driver and was complimentary on nearly every drive on its length, even if it wasn't straight. I know his yardages, since I was caddying at the time I had to keep track, and while he was always near 300, it was not that often that he hit much over. Everyone who was in our group, and even others in latter groups talked about Brett's drives. Based upon the fact that we were in a championship flight, I would wager that not too many ams out there are killing drives over 300 very often, let alone 400. I don't want to accuse people here of falsifying stories, but this is just my $0.02
