It's easy to say that comp footage is played out and that it's much cooler to see backcountry stuff or whatever. But, the fact of the matter is that in the east, some of the best terrain is at a comp, and it is there that athletes get a chance to try new stuff. If you go to Tremblant or something in the dead of winter and ride their table tops, you won't see too much experimentation going on because the table tops are blocks of ice. Good luck building a backcountry booter unless you're lucky enough to be skiing one of the three days all year in the east that gets 12'+ of snow.
HOWEVER, if you go to a comp, chances are that if it's run properly that the jump will be shaped to perfection, the landing slope will be ideal, and most importantly, there will be a groomer not more than a stone's throw away ready to churn up that landing like a pillow. It's at times like these where MANY of the eastern athletes that I know progress their skiing. They have no other choice.
I think then that it's pretty obvious that comp footage will always play a big part of any movie. If not for the above reason, then for the simple well-known fact that people put it all on the line for a comp when there's money and pride at stake. It's not the same as when you're just farting through the park at 10 a.m. ...
