Spent the last several days looking over this forum for opinions on these two sleds. Found alot of great information, but not exactly what I was looking for. I put a X3 track on my summit this summer so it is strictly mountains and deep powder dedicated. I am wanting a sled to run trails, Jump water bars and take to the mountains when the snow is set and wind blown. I have no intension on installing a turbo or s/c, but want something that will handle the bumps. My only experience on a 4 stroke sled was a 07 short track Phazer my buddy got his daughter last year. Took it to Summit ( Alaska) and had a blast. Snow was set up and took turns trying to make it up the face of the Tit. never made it more than 3/4. So I no the phazer is under powered but the nytro is heavy. Would apreciate any opinions I could get. Thanks Fred
