Mounting Rossi s4's and Armada JJ's

Alright so i am about to mount up my sticks for this season and am wondering where i should mount them...
I am 155 6 foot type 3+ skier form the midwest

JJ's- they are 185's and i will only use them in the midwest if we get some snow or if i feel like screwing around. However i am in vail for 15-20ish days per year where i charge hard and drop some cliffs. I will still be skiing groomers on the though. Factory recommends -5 but i was thinking -4 because i will still be hitting some bc booters and doing some jibby stuff on them. I am mounting them with sth 16's.

S4's- these will mainly be my park sticks but i will still be shredding groomers on them. I have heard a lot of people say to center mount them but i think i want to goo +6 from recommended so i can fly pass my racer friends without having to fight the sidecut... I am mounting them with look px12 jibs.

Any advice appreciated.

+K for bumps and advice

Thanks A Lot!!
