Rocker makes skiing easier. I like it in my skis and I have tip and tail rocker. Im an east coast all mountain skier. Bumps, woods, on trail and some park. But, I don't like a ski with too much rocker. It depends on the conditions.
A ski that's rockered like crazy is great in the bumps and pow and trees but I like my Volkl kinks because it still has a decent amount of camber underfoot. But an all camber ski is nice in the park, they have two different feels. Depends on the conditions really but I find myself only skiing my kinks and I skiied my blends once , from two years ago so no rocker full camber and said fuck this lol.
