i started rollerblading before i started to ski, and doing rails with only that 1/5 of space to land on, really helped. when i started to ski i would almost never hit a rail and kind of drift off to the side as you see some beginners do. 270 out's and such came easy as pie, the first time i skied i was nailing them. spins, i havent really tryed with skates im not sure why, but i imagine it would help with skiing.
