I always said Vivid was the best edited Snowboard movie ever! Teddy Bear Crisis is the best one for skiing i reckon!
from the trailer, id say picture this so snowboarding
and for skiing, its kinda more difficult. There are films like idea that are filmed really well, but as far as editing, its pitty lame so i'd probably end up saying it'd be landis' big easy camp edit, because of how great the music fits and how well everything slots together.
