im not sure about dylan and marty.
I Know berman filmed up at sugarbush and i think sunday river so he could have filmed wiht dylan hood then. Maybe he filmed with him at mt snow though, im not sure.
I also don't know about marty, I have no clue how good marty is trick wise (ive never skied with him), but i know he is a madman in the moguls, but it sounds like you know him so he may be sick trickwise, i just have no clue. dunno if he filmed with berman
dylan though is defiantly super stylee, we have some footage of him at mega mother hucker and from sunday river
