I had no intention of buying another sled this soon. I was thinking about a crosstrek but had a ZR in the back of my mind too so I figured I'd wait a year or two and see what came up. I knew I wanted the 137 track and since they added that to the ZR lineup and since I'm a trail guy, I figured it was worth considering.
After I rode the XF this season I really liked it, and compared to the 4 stroke viper, I realized although I thought the 4 stroke would be a better trail sled option, I realized I liked the way the 6000 felt better. I didn't ride either of them overly hard, I guess when you're only on them for a couple days at a time I don't have the confidence railing through the corners and knowing what to expect. That said, I think with a little time invested into a set-up, maybe some new carbides, and some more seat time I think I will like this as well or better than the f8. The crossfire was good for the little off trail I did, but as you would expect the f8 was better for the trail.
