Where is you limiter strap adjusted to? if its too tight it WILL put too much pressure on the skis and make it dart all over. Mine used to dart all over but i managed, i ended up finding a set of precision skiis on ebay, not the pilot but the precesion skis from 02-06 skidoo sleds, the ones with carbide on each side of the ski, that really made a difference this year, i also took off the stock track and put a 1.25 track on it, that helped too! (not trying to get personal here...) how much do you weigh? i am about 200, and my sled handles like a dream. if interested i can give you my whole sus. set up and you can go from there?
