I replaced my stock Polaris Xlt skis with a set of black/purple Simmons flexi skis a couple of years ago. It really improved the steering on the trail since it eliminated the "darting" following of the other snowmobiliers carbide runners grooves. Right now I am looking to upgrade my track since the lugs are quite worn down on my track. Its the stock 133.5 inch (0.82 inch lugs) and I heard that you need to put in a 136 inch track. I was wondering what track is best for mostly trail riding and some lake riding? I have looked at the Camoplast Ripsaw 136 inch 1.25 inch lug as a replacement. I am not looking to stud it since I live in Minnesota and that would limit me to riding only on the unpaved trails.
