First off I will say that I am from the east coast and don't know much about pow skis. I realised lately that there are 2 kind of pow skis. There are some that are really soft noodle-like (hellbents etc.) and there are some really really stiff ones (gotamas and stuff). Why is there such a big difference? Which one is good for what? I always tought a pow ski had to be a noodle but now I'm confused. Thanks
