So I bought a pair of 09/10 Rossignol S4's and I mounted some FKS 120's at +3. I ski probably 75/25 park/all-mountain, but in the park I do a lot of rails, probably 60/40 rails/jumps. Should I get my bindings remounted to say, +6? Or will they be fine? I skied a center mount ski last year, so I am kind of worried.
