It's not that I don't like the 900T, it's a great sled. The biggest thing I dislike is the ergos, I don't like how the sled keeps pushing you forward and it just sits to low for me. My knees ache after every ride. Plus, I like to mix it up every two years. Polaris has been my favorite sled to date, so going back to it this time around. I miss the fun factor that chassis provides.
