I have a 2011 XTX Nytro and love it. 4500 miles on it in 2 seasons of trail riding. Not much of an off trail rider myself, and it's not fun getting it stuck (heavy 4-stroke). But you're probably well aware of that with the Rage... I have the stock 1.25" track. Make the trade and get it. You will not regret it. Interestingly enough, I had an '07 Rage GT that blew up which prompted me to buy the XTX brand new.
The only annoying thing is the 7.4 gallon gas tank. I've sweated it into a gas station a time or two. Never run out yet though. Consider getting the gas caddies accessory if you do buy it. It's basically saddle bags with 2 gas cans inside. You can use one can and remove the other can to store gear.
I have a higher windshield and air deflectors too. The stock windshield is just a decoration.
Overall, I just love the sled and it's great for trail riding. I've ridden across the U.P., alone, on it because I trust it won't leave me stranded.
