I have a 03 ski-doo 800 zx chassis stock except for a can, It has a 144 track on it. I'm going to lenghten it, I haven't deciede to what size. I'm 6' 5" 215lbs My buddy has a 162 I think it is too long and hard to turn. What track will you recomend for riding in the mountains in powder in Idaho and Wyoming. Can I fit a 16" Is a 159 easier to turn than a 162. Where is the best prices for rail/tunnel ext. and track also what kind of track. I know everyone has their opinions and thats kinda what i'm after.
