I just snowchecked a 2015 Pro 163. It was a hard decision, but in the end choose the Pro. I am coming off of a 2010 m8 162. I chose the pro for the same reason most people do. The lightweight mountain design. I ride the mountains only. Couldn't care about trail manners as anything is better than my m8 on the trail. The customization and the golden ticket helped alot as the warranty in Canada is lacking. The fact that out of the box this sled is setup for the mountains is great. I can just pull and go (correction free electric start for the first couple rides anyway). I like the idea of not really having to by a can and skis right off the bat. The powdercoat should help the snow buildup. There has been no major changes in the last while, so I figure it should have the bugs worked. Motors have been pretty sound in the last few years from what i have seen. Almost forgot close to $3000 cheaper than the skidoo and cat I checked into. Don't know why it was such a hard decision to change the brand you ride. Cat made it easier with there high cost and all the extras I would have to buy for it. Looking forward to next season. Better be a busy summer or I am going to go crazy waiting for snow.
