As you note, you're just howling into the wind devoid of any
factual indications of relative security --and one might surmise
that the "relative" aspect is the only place that one might see
a difference : as in being "more dead" from being hit by a truck
vs. a car.
Further, you seem fixated on the securing of the
tail --i.e., its
last-segment-in-the-nub-- : but one might prefer security to come
earlier, on the tail-side eyeleg's passage into the nub ; more grip
here should result in less of that leg's delivered tension to the
collar (and therefore less pressure upon the SPart, depending
on how on sets the knot --lightly or SSnugly!
(Recall that in the Brion [sic --it's an "o"] Toss video of Spectra
12-strand 5/16" line pulling out of the
dbl. bowline it was the
SPart-side flowing through the double turNip and not the (stoppered)
tail that proved its undoing --a difference of nip of the tail, one
must guess, would be academic to this problem!)
