It was probably the crappiest snow you could ride in. It was hard as a rock. I have a 12 with airframes and tied clutch. I couldn't tell a nickels worth of difference between the two. I swapped back and forth a half a dozen times and finally came to the conclusion that there is an ever so slight difference in the ease of tipping the 13 up. The airframe running boards are nicer but the new ones are probably not worth swapping out unless you just have money burning a hole in your pocket. The biggest thing for me was the short seat. It is way nicer to jump side to side on. As far as power my 12 came out of the hole pretty much even and got the 13 by 2 lengths at the top of the hill. The belt drive is a little noisy. my cmx drive never made any noise. Seems like the belt is overly tight. The 5.1 is a joke on the stuff we were riding. It was pointless to even take my turbo. No hookup what so ever.
All in all the took an awesome sled and made it better. If you have a bone stock sled it is probably a no brainer but with a low mile 12, with airframes already, I'm not sure.
