Thanks SJ.. I re shimmed my SLT's and kind of thought about moving the skis.. Mine seem to be wearing more in front.. Put a thicker shim in. Mine are in the forward hole putting the ski more towards the aft or rear of sled.. Seems like the carbide needs to be forward more.. BUT I will wait and see what slightly thicker shim doesalthough I havent run them I believe the concept is the same...forward hole moves more ski aft making it "trail" more and less bite and dart....moving to rear hole moves more ski fore....making it bite more and becomes more prone to dart..
