Well, I just got Polaris EZ-steer carbide runners for my snomobile. I am going to install them next weekend. My dad said instead of studding my sled I should try these first, they should help a bit with steering(especially crossing roads). I'll let you know how they feel. By the way, my Polaris is a 94 and I havent broken 1,000 miles on it yet, mines the "baby"....all the other sleds have over 2,000 miles on them
