Please dont ever use a SUP for comparison!! It shoots your cred in the foot instantly!! haha. (sorry man i live in hawaii, those things are a plague upon the earth)

I dont really have much rocker on any of my boards. I generally go for as flat as i can get them. But for the record i do really like that fish you made CT. It looks fun as can be.
