the ones with camber will have better control on groomers. the early rise makes them so they don't hook on turns and can butter better. this is why it is becoming popular in park skis and all mountain skis. generally, the ones with only rocker will be better in deep snow and powder, yet will have some trouble on groomers and hardpack.
