There is this little race run up in the PNW for the last few seasons (twenty-something), maybe you heard of it. The Mt. Baker Banked Slalom. Quite a few of those guys run rockers and hybrids. The guys on Alpine and BX set-ups tend to get beaten by guys on regular old snowboards every single year at that event.
I'm pretty sure Temple Cummins won Mt. Baker on a billy goat (camber).
