I just bought one, but i have heard that they are decent on trail (i.e better than an RMK) and decent on the powder (not as good as an RMK in the deep). However, throw 2" track on it for the mountains and you will be an rmk. Its a middle sled. All around they are great and fill their purpose well. For really good trails, get an XC for really good mountain, get a RMK.
I here the suspsenison is good and it does turn better than a 136 with strait rails and floats better than a 136 and has about the same push, but perhaps a little less overall.. I have not heard one complaint. I am excited
