Personally, I wouldn't like climbing with some great hunk of alloy ready to bash me in the head/face anytime I step up and over a few limbs (like unicender).
I'd like a device to be compact like the lock jack. Tear drop shaped so it doesn't get stuck in forks or palm butts. Idiot proof so if I let go it grabs.
What makes friction hitches work for us is the fact that we grab the knot and drag it with us along the line. This is fine on DRT but SRT they tend to bite too hard and get stuck ... hence the necessity for mechanical devices.
I want a device that doesn't have anything hanging out of it like the lockjack, no handles, no strings/ropes etc. |
