As you can tell by my name, I ride ski-doo, but I really like the 5, 6, and 700 XCSP's. I know that the 600 and 700 go pretty good, but what about the 500. What kind of top end can you expect from the 2000 (45th Anniversary Ed.)? I weigh 230 lbs and my concern is that the sled will be underpowered for my size. Any info would be appreciated.
