Yet Another Bowline

At the suggestion of SS369 I tried the bowlines with my AmSteel Blue 5/16 coated dyneema.

I loaded them with my body weight, about 150 lbs. No surprises. Everything held.
They are all bowlines, after all.

1. This was no real test for that material. There is (or was) video
   of 5/32" like cord just pulling through a Dbl.Bwl !!! --amazing
   to see.

2. The climber’s concern is security-when-slack, loosening as one
   climbs --not in the fall (unless it’s 2-step : loosened & capsized).

“commonly executed” ? That verges on tautology;
were the knot presented better, it would be better
executed --i.p., in the usual quick-tie method, where
the common way leaves the line dropping unless one
takes extra care to handle it, but the "better"way would
see the SPart supported by its crossing part quickly formed.

The common quick-tie method is common because it’s noticeably easier to pinch the standing part and twist your wrist outward, than to pinch the standing part and twist your wrist inward. It’s an ergonomics issue. An outward wrist twist allows you to twist past the plane of the “page” view to force the half-hitch structure into being.

Perhaps we’re thinking of different “common quick-tie” methods?

What I have in mind is esp. suited for a climber tying in:
having reeved the line through the tie-in point,
and holding the SPart with the left (non-dominant) hand,
and with some tension on the SPart to draw it away/down,
the dominant hand --holding the tail-- reaches out under
the SPart and quickly turns back over & down into the
just-formed loop (of end crossing SPart),
and then continues outwards --which casts the central
nipping loop into the SPart,
AND has the SPart now resting upon its crossing part
rather than dropping away from it uncontrolled.

The common method I see has the reach being done
going OVER the SPart and down-around-up-&-out,
and the SPart just falls out of place w/o further precaution.
(If the line is much in tension away, either works, as
that tension will keep the SPart in place.)

In the standard EBDB, the wrap goes outside the collar. See Fig. 23.

If the wrap is inside the collar, then the rope flows naturally into the SS369 finish. I know it is overkill and a puzzle, but this is the kind of loop knot I would want if I were ever to dangle at the end of a rope.

If the premise were true,
then I can’t come to the conclusion
–why should anyone want such trouble
and inefficiency, beyond need?!

For knots that I’m tying, I hope that they don’t
look like what you showed (for the sake of clarity),
where so much stands in need of tightening,
but which in that case of excessive tucking
will require much care, to the point of tedium! :
