Had 2 Pro's, I weigh 225 , 6 ft, loved them both. Ridden XM's lots, rode one yesterday 3 ft powder , also hopped on XP, and Pro, same snow same day. Me , I think the Pro is just way more fun and easier, this more power story, bull, and if it's true the Doo better fix their power transfer to the snow cause it ain't working. The Pro is right there and many times ahead.
To me , the XM is a XP with a 36 inch front end and a built in initial lean of a few degrees, then it's just the same old Heavy planted XP. The "heated dash storage" sucks at best, the steering is kinda goofy, especially if you're taller, and the clutching is weak . Great gas can and storage bag system, nice motor.
Interesting to see how the 14 Cats do this year, seem to be much improved.
Buy what you want but don't be afraid of the Pro, it's a great sled, especially for the mountain riders.
