Great! very clear! I like it!
(you haven’t introduced the “Anti Bowline” yet, you could refer the reader to the right page)
I agree with you,(http://igkt.net/sm/index.php?topic=5490.msg37331#msg37331)
but we have to notice that the ropes we use today are not the ropes used by Ashley, if we tie a #1010 Bowline with a right-handed (twisted) rope (see ABoK #106), the collar follows the torsion of the rope (in a right-handed fashion), but if we tie a #1034 1/2 Bowline with the same right-handed rope, the collar goes against the torsion of the rope (in a left-handed fashion), maybe for that Ashley named the #1034 1/2 a left-hand Bowline (maybe!?)…
I see, Mark, but I don’t believe that! 
(for that I’ve noticed that I haven’t changed my mind and you haven’t changed your mind…and I don’t know if we are able to do that )
I say it again: I’m not able to demonstrate what I say :-[ and I think it depends on the rope used too, but my personal classification about the stability of Myrtle-AntiMyrtle is:
- Myrtle (opposite handedness loops)
- Anti Myrtle (opposite handedness loops)
- (?) wrong Myrtle (same handedness loops)
- (?) wrong Anti Myrtle (same handedness loops)
I think that 3. and 4. are unstable! 2. is better than 3. (Dan Lehman said it too see http://igkt.net/sm/index.php?topic=4480.msg38446#msg38446) so to my mind the opposite handedness is a principal factor. Surely the stability is improved if we tie double nipping loops!
Last note: why do you talk about the Lee Zep Bowline in two different times (p.31 and p.52) (and the first time before you talk about the Myrtle)?
(in the index you call it Lee Zep Bowline (p.31) and Alan Lee Zep Bowline (p.52)).
Hope this helps.
ciao and thanks,
