him doing the double backflip is similar to a snowboarder doing a 1080. but i think the double backflip was strategic. a lot of guys were having trouble staying on the line through all the jumps. you almost always drift and have to land/take off on edge snowboarding so being able to come in straight and land straight with a fairly difficult trick was smart on his part.
backflips are easier on skis in my opinion. you just have to pop and send it back. snowboarding theres different axis's that can come into play depending on which way you throw it.
