In over 10 years, I can only think of one time that mine has been disconnected by the trees. Maybe twice, but I was in such tight trees that I was not going fast.
I can think of several times that it has saved me a lot of money. Stuck throttle and I am supermaning on the sled and if I had not pulled it, the sled would have hit some big trees quite hard and it would have cost alot to fix.
Last year, my kitty used up a life when I attempted to drop down onto a little ledge while in a sidehill in Cooke, left ski came down and she took a hard left. Usually I argue with myself, you should bail........., but this time is was get the F off now. I landed 3 ft from the edge of the cornice with my feet almost sticking through and the sled dove 25 feet off the cornice nailing the open hole in the creek along with the huge boulders. If it was not for the tether, she would have kept sucking in water until someone hit the kill switch. Needless to say, I broke the muff pot bracket, added 2 one inch cracks to the hood, and sucked a little water in that we were able to drain there. I rode it out with three of four plugs working and was able to climb everything I needed to. I was lucky with the sled and with my life. If I had gone with it, there is a good chance I would have been killed or severely injured. I have also received a concusion in that same creek bed. I think I should ride other places in Cooke besides there.
