Replying to Mounting help please

so im gonna mount my 163 chronic crips with marker griffons in a week or 2 and i am really struggling with where to mount them. i ski in pa so that means a lot of park. i love to ski pow on the rare occasion and challenging terrain so i was wondering if i could still do that at center. but i do ski mostly park cause pa mountains are garbage except seven springs. so i guess im around 70% park and 30% other but i never went center mount and my local shop guy said u lose a lot of ability to ski pow and hard terrain. i know people are gonna say search bar and i did already i just really wanna get the binding position right so where should i mount them?
