le Voyageur,
Could you elaborate some more on your scenario that this knot is being used to resolve?
From the knot itself, it appears that you just need two loops to clip to. To do this, you could have used a double figure-8, a bowline on a bight, or multiple figure-8's at different positions.
In the past, I usually just use a tether to the other person or tether them to an anchor. If no tether was available, I used multiple figure-8's.
Just curious, I haven't done any lead climbing in 10 years. But I still like to learn.
