Abok#1443, single carrick, link bowline
First image, illustrates a 1443 based initial dressing state, tied as eyeknot of course, and a pseudo final energy state, not the final energy state Ashley depicts for 1443, but a transformed equivalent topology (for Ashley's result, just load the initial dressing state from the Spart and the returning eye leg).
In any case, these "half knot configurations", as i call them, with the 1033 components in a reverse usage (simple loop as nip, crossing knot as collar, in contrast with 1033), could not be considered as being the stablest forms, while Ashley points out, that the corresponding bend, slipped with medium loads.
This is an attempt of completing the depicted pseudo final energy state by constructing a stable bowline structure.
For those who are not into initial dressing states or transformations, they could simply insert a bight down through an S nipping loop, feeding then WE down through this very bight by capturing nipping loop's crossing point.
The next coherent step is to form the collar and come back up through the nipping structure.To track down the tibness, is to rethread WE down through the collar structure channel, in a side by side two end orientation, as shown in the next three images.
Advantages
1. A TIB bowline.
2. Three rope diameter in the nipping loop.
3. There is a non-jamming collar due to the crossing knot link geometry, which grips its continuation.
4. If you hold the tug end and pull the returning eye leg, you create a nipping loop slack which i find a useful property for the untying process.
Disadvantages
1. A rather complex collar structure, in particular at its link segment.
2. I'm not so sure about the EEL ability, because due to the fourth property mentioned previously, it may not be wise to load the knot from the WE, in reverse.
