Where to start, been riding for 15 years. Have owned Ski-Doo, Cat and Polaris. Have bent, mangled and or sunk Ski-Doo's, Cat's and Polaris's. Last year rode M6, RMK 700 and Summit 800. All 3 sleds took me all over the mountain. Some just take a little or effort than others. Did manage to tear the pipe off the RMK in a midair collision with a tree. Rode it for 2 more days with duct tape and wire (sounded better) It's not the sled, think back 15 years, heavy summit 670's with 136 tracks still went all over. It's the rider
