everyone needs to check out this website. I was in Laax Switzerland on the weekend and they had this huge air bag thing that u go off a jump and land on the bag, its like the one they use for stunt doubles when they jump off the roofs of buildings.
anyways is was amazing and i learned tricks that i never would try on snow. Personally i found it even better than water ramps.
