I'm going to get a new sled this year. I rode a buddies 04 summit 800 with a 144 and it was awesome. I want a little more track, and am thinkin about getting the 151 and then putting big wheels on the inside of the rails so it will handle similar, kinda. I'd imaging the bigger the better but don't know. My thinkin is the 10" would shorten the contact surface just a bit more then the 144 and also let the track spin more freely. Who offers the best kit and any extra info would be great. thanks
