i think most people have trouble 'accepting' no poles becuase its such a radically different style than they are used to.
in the 80s and early 90s, if you werent wearing skin tight ski pants or jeans, you were fucked up. people didnt accept baggier pants and jackets cuz it was so much different than what they were used to. same with tricks. daffies and spreads were the shit for a while, until someone tried doing something new. first, grabs were considered to be horrible style; same with off axis spins and stuff. however, as people got used to seeing them they began to like it more and more until it became the norm.
its the same with poles. no body needs them, everyone just thinks you do. once people realize that and accept it, everyone will be skiing with no poles and everyone with poles will be the old guys still stuck in the traditional mindset.
its the cycle of life guys, c'mon. everyone should just ski how they wanna ski and whatever trends arise, will arise. but just keep skiing how you wanna and dont worry about everyone else all the time. shiiiiiit.
maybe i misunderstood the 'free' part of 'freestyle skiing'...cuz that implies that you are free to do whatever you want, however you want...
