Replying to True center mount or 2cm back?

im wondering if i should go 2cm set back or true center mount... i got the AR6 (which are not TRUE twin tip) and i'm not gonna spend all my time in the park... about 50/50 i'd say... so im leaning towards 2cm..

but will it make a huge difference when jibbing? what about spins?
also im looking for all-mountain, some pow, etc...

sorry if this topic was already discussed, but i wanted to give you some info on what im looking for... and some questions too..

any suggestion is appreciated

thanks!!
