Hi, I'm looking to get a newer sled but I'm not exactly sure what to get. I just started getting into mountain riding last year on a 2009 XP 600 etec 146. Now I would like an XM but not sure what to go with for a track. I'm 6 foot and 220 without gear. I've been told to got with a 163 because of my size but I still wan't a nimble sled that's easy to throw around. Is the 3" that big of a difference over a 2.5", I keep hearing mixed reviews. I'm also thinking about a Freeride because of the shocks it comes with. I'm mostly looking to ride in the mountains, not too much in the prairies. I'm more into boondocking instead of doing big climbs.
