I had the same delima when we got beyond the inital stages of riding. So when I shaped my own, I took the best of both...I think. The rails are sharp as a razor and my current board is 4'2" long and about 2.5" thick. At almost 50, I'll never do pop shuvit's or the like. Although my son James can and is working on body varials with his. I prefer the sensation of surfing and really like the way a surfboard carves. I too had the same expeeriences as Ryan with the broadcast and some skimboards...it was TOO MUCH WORK!
I also found that you don't need a 6'7" board for wakesurfing...that extra length is required when paddling into a wave, but not needed in this sport.
I'm sure you remember the thread where we talked about those prototypes Elliott. If you get a chance, scan the pictures post thread, you can see James catching air or doing a cut back on his board.
