A downside of using the escape eights in this application is the thin construction, with a small bend radius.
When the 8 is on an eye completely different configuration, there’s no potential to slip to a girth, the ears would get in the way of the desired functionality.I could see the bight on the ring slipping and becoming a girth hitch. Ears on 8's were developed to eliminate this possibility. The mini 8 above looks like a good choice.
The version of it without the webbing has a tiny hole that no normal biner fits, as I remember. I think only a shackle or quick link would fit. Its also double action and will let go after the second trigger unlike a biner. It has promise though, I like it. I just wonder if it would stand up to abuse, tolerate cinching well. The instructions do say to not hang it from a rope loop or side load it on an edge, the latter not being a surprise.My buddy Josh was talking about a ring on his lanyard when these things came out. I kind of like the idea of being able to just slap it in until it holds.
For me the question is can it be choked tight on the spar or limb/branch and loaded down, sideways or whatever direction you wanted to load it. Looks like it could be.
If you wanted to be extra hardcore you could clover hitch it or munter it ... but that actually seems to hold pretty well. I’d say it would work on anything over 3” by the looks of it. Especially if you’re using a thinner (<11mm) ropeFor me the question is can it be choked tight on the spar or limb/branch and loaded down, sideways or whatever direction you wanted to load it.
