That is a really good rope. My Safeguard has never slipped. In the video I posted above I tied a slip knot before climbing with the Safeguard. If tied in the proper direction and the rope slips, the knot will jam in the Safeguard. I like backups just in case. If I am already setup to do it I usually will.I just ordered this rope from DanO 9mm.And safeguard. Thanks for your help
