So i figured this out.
If you start off (learn) to ski with no poles, then later in life when you get poles, your style will be better.
Think of TWall, he rode with no poles in his superunkown, which wasnt that long ago, and now that hes pro, he has the best style in the game. It's because he rode with no poles for most of his carrer.
I figured this out because when you have no poles, your arms stay near you when you balance. So when you get poles, your poles help you balance, but weight more so they have to be lifted higher and instinctly go higher and farther away to keep you from getting stabbed.
