that's totally false. i would have believed you like 6-7 years ago, but park skiing is at a level that is equivalent if not better at training kids how to ski than any other discipline. Candide won the FWT he's a park skier. and gymnast would not be able to carve lips, ski switch at all, or understand the nuances of style. i think rails and jumps both require good balance edge control, proper stance/vision, air awareness, and style... these are the aspects of a good skier and can be applied to any discipline. I can do much more on rails, i think being a rail nerd is legit if you can still throw at least some steezy shit on big jumps.
