Winner of the needlessly deceptive feature name goes to K2 with the Catch Free Rocker, which really means the board is 90% flat camber... but raises (or rockers) just the nose and tail contact points. Which when compared to any regular camber board, the contact points are debatably different on a completely flat table surface... let alone on a snow covered hill.
If I hadn't looked at this in a store and realized it was actually flat, I wouldn't have bought it. Actually, I wouldn't have even considered it because I didn't want to buy my son a rocker. Imo rockers don't teach good board fundamentals as well as a regular camber, or even a flat (like this board).
K2 - turn off the political news and skip the marketing spin. We get 'rocker' sells, but so do other things.
