Dan,
To check: It looks like you effectively have the ring going through two back-to-back symmetrically-tied overhand stopper knots. Yes?
Um, mirroReflected Overhands, yes,
in a sense -- for, really, this
notion began as a sort of variation on the Bull Hitch, bringing the
bight around and
between the S.Parts, and then ... I wondered
how to get the bight-tip to lie within the knotting, against the ring
(and I had thought it must be TIB, but tied it longhand (which can
be quickhand vs. trying to solve the TIB question!)). And, with some
loosening, viola, the Overhands aspect appears. But
set, it will
look more like adjacent Half-hitches (which, yes, for a HH noose, is
what an Overhand is (topologically)).
I think that the "rat tail" material will, by its somewhat *puffy*
compressibility, enable the hard-set knotting to shrink diameter
and bulk and visual presence a little, and stay tied!?
