I've never been brand loyal to anything. I become loyal to what works the best at the time. I have owned several Ford, Chevy, and Dodge trucks. At the time, each was about the best out there. Things change, advances are made, same with the sleds. I have only ever owned Cat and Poo. For me the Yammi's are just too heavy, and I can't currently afford boost. The reliability would be awesome though. I can't do Poo right now because they are burning up way way to many engines. I love the IQ raw chassis, just don't want to have to deal with problems, or even take the chance. I couldn't do the Rev because it seems like the motors have issues, broken nuns, and flimsy running boards. I have buddy's who swore by them, but they bought new ones every two years too. Maybe the XP is different, one of my buddies rides one now, on his second year and no problems, his dealer seems supportive. The sled doesn't impress me much for being so revolutionary, but I may try one. I just watched too many ZX's and Rev's broken, I can't do that where we ride. I am on a Cat now because I think the engines are the most reliable, most moddable, and I really like the M chassis. Works for the way we ride, even though I curse it on the trail. Wieght, reliability and fun factor are my top three.
