It is hard to say. What have you skied before? Mounting position is basically all preference. If they were my skis I would mount them at true center, but that is because I like the feel the best. Someone else might love them the most at -1cm from true center, and another person like recommended the best. It is completely preference, other than the fact that you will want them somewhere between true center and recommended. I can't give you anymore advice than that.
