Schifty, do you leave your coupler blocks out for trail ridin' too? What sled do you have -- std or sno-pro -- and how much do you weigh? I weigh 140 lbs and took the rear couplers outta' my '02 800XC and for ME it was a HUGE improvement in weight transfer, traction, ride quality and fun factor! My first impression of my F7 though, is that it has more than enough weight transfer, and the ride quality felt pretty darn good too! -- Roy
