Arctic Cat added a coupled suspension 2 years ago or so for that reason. In the past, w/o the couplers, there was WAY too much ski lift for racing applications (needed more track on the snow). So...they added the couplers to eliminate this. Regardless, none of this means a damn thing. All of us ride in a different position, have different weights, and have different thumbs. One set-up does not fit all!
