I am a forward directional rider. I mounted mine at team line, which is 2.5cm behind center in 183 length. In powder I have not had any nose dive and the ski handles fairly well. I still get the feeling that there is a little too much ski in the rear however. I am considering mounting another cm behind current position. I think I need another couple of days to decide. Hope this helps.

I have mine center mounted, love them like this, ski still floats like a charm, and landing switch is as easy as any ski ive ever owned. If you into back country freestyle id go as close to center as you feel comfortable.
