im pretty sure that was filmed for sherpas new movie, hence nobody really hearing about it. i think sherpas posted about it on facebook back when he did it though.
im pretty sure that was a triple... he had so much time after that dub and when it cuts to the last spin/flip he's in the same position as he was at the end of the dub... not sure what to beleive
that was at whistler... and that was a north face ad, sherpas is now sponsored by north face, hence wallisch being in their movie, so theres nothing they would be pissed about.
North Face had to get the footage somehow....so Sherpa's clearly agreed to it. Plus, it's a two year project, he's bound to do another one before the release of their film (especially with Tom doing his own project this season).
im convinced that fie first shot is of a dub 12 but when they change angles the end of the shot is the end of a switch double rodeo 10. cuz it doesnt seem like the rotation of a triple cork at all.
