Using #1410, backed up with the same, snugged to the first (so easy and functional),
I had no challenges with any aspects of use or undoing.
Way easy to teach as well.
While my initial reaction to the so-called "EDK-backed EDK"
was unfavorable and like that expressed in this draft paper,
I've come 'round to realizing that in fact this arguably
needlessly bulky knot has much to recommend it in
terms of NOT needing the "IMPORTANT!" tying points
given for my once favored variations of the EDK/OOB/OWK
of how to position different diameter/nature ropes and so on
--something I'd challenged myself with, to wit : "If THESE
tying fine points make for *better* ..., does missing them
imply *worse*?!" (likely so, alas)
At the very least, the
OOB-backed-OOB" (to avoid "EDK")
should be advocated as a brain-dead method for at least
stressful times (for cold & gloved hands with stiff ropes, e.g.).
Where all bets are off on assured dressing & orientation.
(I've yet to test the compound structure with cases of
egregiously unwell-tied knots --misoriented, crossing strands,
and NOT snugged up well (maybe slightly loose, to boot);
my contention is that, though, the knot WILL hold in such
cases. And that THAT is one BIG point in its favor,
all ugly aesthetics aside!

I am of average weight, sometimes do a bit of wild things on the way down for fun,
but I know I don't stress the rope(s) or my gear anywhere near their limits.
It's important to consider the effects of such circumstance
which might seem benign & well within safe tolerances,
when in fact it might be that precisely the lack of force
upon the knot enables it to do things re loosening!
--this, at least, is what was asserted/mused/theorized
for the loosening of (non-offset)
water knots in tape;
that once hard-set, they behaved well; but without that
setting, they could ratchet loose the exterior strand.
(There was a death from such a knot coming untied
last year, July? --an Exum guide.)
Not sure that offset end-2-end knots have such vulnerability,
but running through some combinations of ropes and dressings
might be best done first with say 50# force gently bounced,
then bump up to 100# or one's body weight, and even some
doubling of that w/pulley assist or other means,
seeking happy upper reaches.
For my part, if I get to this, I'll certainly not be striving at first,
at least, for seeing actual knot failure; I expect that initially I'll
be making observations about differences that obtain, of what
forms/combinations/orientation-of-knot seem to be maybe
heading in a bad direction. And then THOSE might get some
kind of more serious test!?
