hi. i'm buying my first set of rockered skiis and thinking about length. i'm currently on a set of 172cm dynastar legend 8000's. i'm 5'10, 175lbs, aggressive skiier. i'm considering a pair of dynastar sultan 85's, not sure about 172 vs 178. i live in the east so the ski needs to be good on ice!
any insight is appreciated, including other recommendations of skis. i like to buy demos that are a couple years old.
