Hope it works well for you. People always underestimate the 600, and yeah, it's not going to beat an 800... until the 800 blows up. I've got an earlier 600 with 4500 miles – runs great, good compression, and the crank runout barely moves the needle. I'd go so far as to say most 600s will outlast their 800 brother 2-1 in hard riding. If you want to be king of the hill, you're going with the 800. If you're just looking for a pull and go sled that's still fun to ride, it's the 600. You'll get the same money or better if you sell it too. Hard to go wrong with the 600, in my opinion.
