Something you like.
No offense, but there are a bagillion threads like this, and the OP gets the same answer every time - choose your own song. Choosing a song is something you should have to do, because only you know what your footage looks like; only you know your style of skiing; only you know what would go well to this edit. Music is critical to the mood/vibe you want to present, and do you really want to leave that up to a bunch of random kids on the internet, all with their own style and opinion?
Bottom line: choose something you like. Something you can't stop listening to. Something you know will go well with your skiing and your style and your vibe. If you're serious about this video, then you should put more thought and effort into it than you have; you shouldn't have to resort to the internet.
I'm sure you can find something on your own - it doesn't matter what we think. Basically, if you're stoked on it, you'll be more stoked to edit it, and the final product will come out much better.
Cheers mang, good luck.
