i have the same ones and i mounted them whatever the factory center was on the ski. They are AWESOME for which ever pow/all-mountain/swithc skiing you're going to do. Now that's personal preference, but you've probably not skiied a ski like this, i'm guessing, so it may seem a bit worrysome. If so, I would suggest you get the jester schizo if you have any doubts. I know theyre a bit more but if you want a true center and then move it back for all moutain, i guess that would satisfy your worries in my book.
