I am about 175lbs and 5'11" ride a 7 on the DIN setting, I currently have Rossignol Axial 120's and I am looking to get another pair for new skis, the SAS2 110 or 120. I was wondering if i really need a 120 size binding even if my DIN is only at 7. I do hit some jumps, but im not doing any huge kickers or cliff drops.
