I ride a 2010 M8 SNOPRO. I had a short ride on a friends 13 XM154 and liked it alot. It didn't seem to want to keep both skis planted to the snow like previous summits wanted to when I rode them. Haven't rode the new Cat or POO. They all have their pros and cons. I think TRAILSEEKERS in SEBA BEACH are havin a demo ride challenge between Cycleworks and Martin Motorsports on Jan23. hope this helps.
