We should have started a new thread I guess but since this one is pounded into dust I will respond. Slick since you own an XP your comments surprise me. Most of the XP guys I know laugh at the whole stability/can't sidehill comments. I wouldn't own a sled I couldn't take into the trees and have fun with. We can sidehill these sleds with EASE! In deep snow it is effortless and you still have the extra flotation and climbing ability of the wider track. I can sidehill my XP on hardpack, takes some effort but it can be done. The difference in deep snow performance, especially in the NW and BC snow, is minimal but nearly everything else the Doo out does the Pro. Power, fit and finish, reliability, ride in the rough, warranty, fuel usage and on and on. Now with the XM all of those attributes are still their but it is easier to ride in tougher conditions. I think it is even better in the deep.
