Another likely problem with this end-2-end joiner is that it can
become imbalanced, with one end getting the jump (so to speak)
on the other, achieving straightened, less-force-impeded passage
to it turn & nip of the opposite end, which thereby aggravates
the imbalance (impeding the reciprocal nipping that would
ameliorate its own delivered force to its nip). With ropes of
the same nature (e.g., tying a single line into a circular sling),
the matter is likely addressable by careful setting; but with
ropes of differing natures, the situation is problematic.
