Berman does have big mountain in his movies, and every superunknown winner has been very park-oriented so far.
It's so true, it's really hard to get good big mountain footage in without helicopters, and booters take a long time to build when you're only up for 2 days a week. Conditions change, snow levels rise (or drop), and BAM, your jump is gone the next weekend. That leaves you 2 less hours to hit/film on that day, since you have to either rebuild or fix the booter.
Anyone who backslaps off a 5 footer cliff shouldn't really be in the superunknown finals...but I guess the park skills pretty much blew my mind so it makes up for it.
However, whipping a camera out of a backpack to film someone hitting a cliff, or stomping out a lip to throw down off a cornice or something takes about 10 seconds, another 5 to turn the camera on, and another minute to hit. The problem is, if you don't make it, hiking up steeps is a bitch. But that's what you gotta do to get a really good cliff shot.
