I run 8" and love them! I did rip one off though but slydog would have warrentied them. it broke right on top of where the thru bolt goes thru the ski. I didn't have time to wait for a new ski so I made steel brackets to fix the issue. it happened when I almost hit a tree and was facing up hill.when I tried to back down the tail dug in and thats what did it. oh well
