your an idiot, dont give advice until you are a little more knowledgeable.
center mounted skis only suffer in performance really in powder, but these skis wont be seeing too much powder im guessing, and even if they were mounted back they are pretty narrow so they wont be great in powder anyways.
i actually like a center mounted ski all mountain a lot. skis that are mounted center give you more tail for when you get sent back seat and makes it easier to recover, being center mounted makes it much easier to throw your ski around making it easier to do quick turns on steeper runs and this especially helps in chutes
