I road doo's, they are straight flat driving sleds and because of this they narrowed the ski stance, i dont know how the 2011s are for fun carvy sleds but the narrower stance makes me think it would be not stable. They really feel like a trail sled thats really long, not a mountain sled. To me my IQ carves like a dream but is still stable, and ive head the pro is the same but even better, and i can see that being its the same geometry but just stiffer. I really think ski-doo should ditch the snow-x geometry and make a mountain chassis or else go to a 15" track and ditch the exterior rear wheels to see if that helps.
So saying all this, the bit extra hp can easily be added to the pro but to completely dial in and change the geometry of a sled is not worth it so ill be sticking with Polaris.
