Haha! Love that critique of the figure 8's, and I agree.
As I understood it, the crux of this thread was to address the vulnerability of the BoB, namely the non-redundant collar.
This knot has no such vulnerability, and its construction seems more suited to ring-loading. That's why I think it's ultimate.
I also appreciate the water knot loop mentioned earlier, but that one is more chunky and harder to tie.
