Techno would TOTALLY work with a ski movie, you just have to pick a good track.
If you don't want 'pure techno' cause you're afraid people won't like it, get some really old stuff that is half rock/half techno. Such as really old Prodigy.
The thing is, 'techno' is such a broad term and means so many different things depending on who you talk with. For some people, techno means techno, as in Chemical Brothers, but for some, it could mean house, trance, progressive, lounge, etc.
So I guess my post is kind of useless, but it totally depends on what sort of style you're looking for. Groovy, epicy, loungy, fast, slow, hard, soft, etc.
