Got my snowcheck sb yesterday, 144 with a 2 1/8th track, fresh out of the crate, took it out on the pond, and all i can say is wow. I lined up with every sled that was there, only sleds to beat me were a studded heavly modded mxz and a turbo nitro. not saying this is the fastest sled in the world, but i beat 800 dragons, stock 800 mxzs, and a few others i forget, sometimes by a lot, sometimes by a half length. Everyone i let try the sled was blown away with how smooth, and fast it was out of the box. Polaris got their **** together this year and has a good thing going for them. Just wondering now what a switchback with a standard track will do??
