i started skiing after several years of boarding. i intended to split my riding into offpiste=board, onpiste=ski. but it turns out i am doing both on both, so almost every day i am spoilt for the choice. ski/board is a 2thirds/one third thing now.
I'll never board because:
1. If I did I'd have to pay for that too and I'm too cheap.
2. I'm too damned old to slam face first to the ground every few yards as I would most certainly do as a beginner.
3. Boarding has always looked inelegant to me. (I know that others won't agree with that. I ski at Baker which has incredible boarders all over the place. They still look dorky to me. Oh, well.)
