Not bashing the Doo, Its a good sled, just doesnt handle as easy as a pro. Thats why people fall off the first time they ride one, because it takes less efffort to ride the pro. Its just works better in most conditions. I would like to ride the XM to see for myself how it rides. As for you's that are spanking your buds on the hills, its because your a better rider, Doesnt matter what you are on. For that fact I out rode my buds this year on their new XP's with my 2008 IQ rmk 700, Its the rider and his abilities.
I have both sleds, an E-Tec and a Pro. Same rider (me), same hill, the Pro will go higher on the hill, especially when the snow is really deep.
