well to be honest i dont know that much about bindings, ive heard good things about look. you have an 85mm waist on those i think, i dunno if you'll need wide breaks but your shop will def give you what is appropriate. I'd mount them somewhere in between true center and recomended, your call on that one. If your a very strong skiier, the extra tail from center mounting probably wont hurt you too bad outside the park, but just think about turning when you have more on the back and you can probly imagine what it will be like.
