Are they good? I'm thinking of getting them but not sure. I'm 5'9 at 175 lbs. Looking for an all Mtn twin tip that can handle any thing I can throw at them (park, bumps, trees, powder, groomers). I live in the east coast, but going on a trip to Revelstoke and Kicking Horse in Feb. What do you guys think of this ski, and were should I mount them??
