Looking at purchasing my first snowmobile. I've been on my dads for a while now. Its a 2010 Crossfire 600. I've got 2 sleds in mind. One is a 2017 Cross County 6000 ltd. the other is a 2014 xf8000. I've been thinking the 2017 is best because I do a lot of trail riding and the shorter track will help with that but its also very capable in the deeper stuff. Is there anything I should look out for on them?
