skiers go bigger because of the phsyics behind it. skiers go faster than any other non-motor sport out there, i can promise you. well, maybe besides bikes, but the pedals are almost considered as a motor. all and all, skiing is a faster sport than skateboarding, frootbooting, snowboarding, ect. thats why skier get bigger air, allowing them to spin more, flip more, ect. its not actually easier, its the physics behind the sport. notice how on flat ground you cant do shit on skis? now take a skateboard, you can do all sorts of crap. its all physics, baby doll. skiing is the man sport, it takes skill, and should be respected.
