Replying to K2 obsethed mounting points!?!?

so i picked up my obsetheds yesterday and they feel sooo dope. but anyways i have a question about the mounting points. i measured and core center is dead center which is crazy. so m,y question is, i am 5'7 and 135 lbs, and should i mount dead center(core center) or +5 which is 2.5 cm back from center? i cant decide, i will be using these for deep pow, cliffs and some jumps. no rails most likely. some switch stuff but not a ton. the reason center is attractive to me is because with less ski in front of me i feel like i can throw em around better, but i dont wanna take away from my flotation. will the rocker on em be enough to avoid tip diving if i mount center? advice frpm people who have actually skiied them please.
