If you do consider the track kit I would suggest the Tatou 4S Tracks from Camoplast. I bought a set last year and put them on my 08 XTX and wow!! I had a lot of fun last winter, Cant wait for it to snow again. There are a few things I liked about the Tatou Kit Vs. some of the others. First, the 4s means 4 seasons. They are designed to run in snow, mud, sand, dirt, rocks...you name it these will do it. However, I do think running them in the snow is the most satisfying. On dirt and rocks the ride is very rough and turning them is tougher but do-able. The pricing was better on this kit that some of the others I looked at. I also liked the quality of the rollers and hardware used.
The other thing to remember is that the tracks are definately not for you if you want to go fast with them on. It takes your top speed down to about 25 mph. But, it really gears the machine low and you can climb like crazy and the traction is unbeleivable.
If your not in the snow much then you will probably like the lift and mudders just fine. Just thought you might like some info on the tracks.
