Re Reply#84. The Lee's Bend #1Z and 2Z are found already included in my folder as Mercury Bend.
Which makes one look closely to realize, as yChan earlier
remarks, "Lee's Bend #2Z is the mirror image of Lee's Bend #1Z"
OK, glad that that's figured.
BUT, in a way, they're different, per Alan's precise geometries:
note that in the 2Z/lower knot, the Tails meet & cross sides
BEFORE running up through the rest of the knot; whereas in
the other case, their Xing comes up within the knot.
Does it matter --and this is a matter of dressing & setting?!
I recall the HowNotTo guys testing --supposedly only?--
Butterfly knots and through loading (so, Butterfly joints),
and all or nearly all of them pulled undone, spilling,
with continual rolling out of material along the way;
Mr.HowNotTo (Ryan Jenks) opined that he'll not ever
trust the Butterfly on account of seeing this.
In ONE case (2?), it happened that #1408 (wrongly named
by Jenks/video as "1452") was tied; surprising to me, it too
rolled, continually having Tails jump from one state to another,
and feeding out material. Well, I THINK that were those #1408
Tails dressed to cross *outside* of the knot and the knot then
set firmly to secure that positioning, ... it would've held, to rupture.
HERE --after searching through a LOT of HN2 videos-- is the case,
at about minute 25:54
