Just calling out a few of my friends for picking up sloppy seconds, nothing more and nothing less... I hope most of you would do the same!
Everyone hits everyone else's jump spots, rails, etc. While there are tens of thousands of rails and even more spots that have never had jumps built on them, there are certain places that are more easily accessible, get more/better snow, are more scenic, and are just more conducive to shooting then others. Who's to say who was the first to do them, or who should be the last, but year after year, a lot of the same spots get hit, and that will never change.
I'd make no secret of it that I look at a lot of the other movies out there (honestly, mostly snowboard) to check out their locations, how, and where they build jumps, etc. Any opportunity I get to learn more, I'm all over it. Its called inspiration. Of course, the best spots are the ones that you discover on your own, but it can't always go down that way, and there will be jump spots that get built up and hit, year in and year out by a dozen different crews and appear in a dozen different movies. Level 1 has shot spots that other crews have been on for years, and I'm sure that spots our films first popularized have been hit and will be hit by others- thats just how it works.
As for hitting a jump immediately after another crew builds and shoots it... I would at least wait for the landing to fill in- then its fair game!
Think snow.
