Replying to Broken edging?

i got a couple of questions here. ive been riding park for like 3 years now, and im really starting to progress. i have dynastar trouble skis with px12 jib bindings. and as you can see below this whole section or whatever ripped out. and im wondering if this is repairable, and im due for some new skis and i want something buttery and light; a nice jib ski. so i think im going to go with the atomic punx. and i was curious what is the advantage of having your bindings center mounted. any advice is welcome.
