Went to my local Polaris dealer today to test ride some sleds. He had a 2011 polaris 800 assault switchback with 144 track, a 2009 polaris 800 dragon 138 inch track and a 2010 polaris rush 121 inch track. I rode the assault first and what a sled. This thing just rocks, lots of power rides very good, works well in the powder making power turns. I could be going 70 down the trail and hammer it and it would still lift the front end up, what a blast to ride. It also handled a ruff section of trail very well I could hardly feel the bumps. I then rode the 2009 800 dragon, nice sled but not as fast as the assault and it did not ride as nice, however I could make powder turns easier with this sled than the assault. I then rode the 600 rush. Kind of a disappointment or maybe because I rode the other 2 faster sleds first because it seemed slow like my 2000 polaris triumph would kick butt on it. The ride was not as expected either. it threw me around more in a ruff section I rode and did not seem to transfer weight very well. It work ok in the powder. I guess I would pick the 2011 assault for sure with the 144 inch track.
