If you flat base at high speeds, rocker between your feet can make the ride more squirrelly then camber I believe. But if you carve, even at high speeds, the side cut plays just as an important of a role as the profile. CRC boards are fine for carving at speed.
I'm not a fast rider, I want something more playful and agile then my full camber board.
I was going to go to like a 155cm board and a hybrid setup, but I'm just confused on which to go for.
