Replying to Set Up question - Please Help!!

im 6' tall and going to be shreding last years k2 shreditor 102's 177cm and use the 70% all mountain / 30% park. I have some new FKS 140's to throw on there as well. Should i mount True Center or like 1.5cm back? I want to be able to use them for when there is some pow too? Not sure what to do. Will they still perform will in some pow even if they are mounted true center? Please Help!! I was told not to mount to far back (2-2.5cm) cause they are rocker and ill whip out a bunch if i land to far back?
