These seem to be more complicated versions of the Yosemite Bowline; do you have any info on that one? It’s been my go-to bowline for all applications (climbing, sailing), yet now I’m wondering whether it has some weakness I don’t know about.
I think the only weakness with Yosemite bowline is if tied wrong. Bowline backed by a double overhand is about as fast to tie and easier to check IMO, but if you are used to Yosemite then maybe it's the opposite for you.
