After a season of enjoying black and double black diamond runs on skis (including my favorite, 65cm short skis), I tried snowboarding. Never in my life of sports have I subjected myself to so many hard contacts as I did in my first few days of snowboarding. Day one I cracked my helmet.
Maybe it's a matter of environment. Fresh powder is like butter, and the board is a fat knife. But on packed or groomed runs, the slightest balance mistake, putting your back edge down inappropriately, result in a whiplash-like fall with nothing you can do but absorb with tailbone, wrists, and head.
Falling on skis is so different since you have control over your legs (even if the skis don't snap off). I've done accidental front flips on short skis and recovered. But on a board, once you lose control of it your feet are barely useful.
Part of me wants to try again, but part of me would rather take risks doing new interesting things (like hang gliding).
If you like skiing, try boarding. If you hate it, go back to skis and be happy. Just because you _could_ do it doesn't mean you have to :).
