Ok so to start off i'm 5'4 weigh 120lbs, i'm an advanced skier outside the park but pretty new to park. In the park i'll be doing like 60/40 rails and jumps. I live in the midwest so i get almost all conditions. I want one with lower swing weight. With me being smaller how much do i have to worry about them snapping? also is the ar50 sidewall on the ar7 that much more durable than the sidewall cap on the punx?
