Replying to Where to mount K2 Pettitors

Hey guys, I have a new pair of Pettitors and some Look Pivots I just got and need help deciding on where to mount them. Has anyone skied the Pettitor before, and if so what do you think the best place to mount it is? A lot of people say I should center mount them, the only concern I have about that is if it will hurt their float. I am planning on skiing switch a lot, in pow too, so a center mount might be the way to go? What do you guys think, I've never skied anything close to center mount though. Thanks in advance!
