I have 2, one is like a flat strop which I have never used and the other is a Kinetic Recovery Rope from Goodwinch which I have used a few times. First time was at Avalanche when Sir Dorris had to tug me out of the slurry, tried normal strap and failed, the KERR worked a treat

Have also used it a few times since to shift others that were stuck.
As already stated you need to have good quality recovery points fitted, even better if you use a bridle to spread the load
