I had a day when I was able to hop back and forth from a 2008 xp to a 2011 xp with the 36" arms. All I thought was "yep, still sucks, just narrower". It really is all about that dumb steering angle. Good to hear the XMs aren't like that. I've got no problem with anything else on those sleds because everything else can be messed with. But that one issue really is that bad. So if it's gone, that's awesome. I even got back on my own formerly owned Rev last year. My only reaction 'jesus, no wonder I sucked so hard when I started this sport'.
