Replying to Obsethed Help

Just got my new obsetheds, and i am going to be mounting them with maker f12s. I am 5'9'' 135 lbs. I ski aggressivly in mammoth. I will use this ski as a touring ski as well as a pow ski. I do not know how to ride switch in pow but it is something i am going to want to learn. Apparently some K2 riders mount them dead center, which might be a bit too much i feel. I was wondering where i should mount them in relation to the center (i was thinking about a in. behind dead center)
