dude, COME ON. if your gonna ski park (and Rails), just get used to the fact that skis arnt gonna last. if your lucky, youll get a season out of them. i frequently go through skis on a monthly basis. it sucks, but its just part of the game. if you can deal with that, go make carves.
besides, thats a pipe ski, and the salomons have narrow edges. figure out where the edge is pulled out to, grind that shit off, and pull the loose edge out. you can make an epoxy edge to seal it, but if you arnt comfy, go to a shop and have them form an epoxy edge. you dont want a replacement metal one.
