i have gonn heliskiing in revelstoke, bc and although it was really cool, I would definetly not pay for it, although its an amazing experience, fresh tracks getting to ride in helicopter it's awesome. But the thing is you ride pretty low angle terrain, nothing to gnarly and your with a group, meaning people you ride with are probably really rich and dont know how to ski that well.
although it must be different with every heli operation i doubt you can ride the gnarliest shit its not like in the movies. still fun as hell though maybe not worth the 700$ a day
