I know rceing helps so mush when ur going down some back bowl and u run into icey conditions and stuff like that. also almsot 100 percent of the skiers that are big right now, and all of the ones that can ski woth a damn includeing the likes of pollard, seth, the entire french canadian group, tanner, ect... . Also the bindings are already mounted but u can slide them forward and backwords and it says speed, all mountain , and steaps for each seeting from backwords to forwords. Im not sure weather speed or steeps would be better.
