Hi, I am trying to decide between a Ski-doo GTX 550F and an Arctic Cat T570. Other then your opinion on which is better, one of the questions I have is: is there much difference between a 136 inch track with 1.25 inch lugs (Ski-doo) vs a 144 inch track and 1 inch lugs (AC). I can't imagine, but I don't know. The Ski-doo is about 700-800 more also. I will be using it more for touring and family stuff but every few months of the year I will be going on LONG trips and hauling back hundred of pounds of meat (hopefully). Thanks.
