Tom,
come on, can't you see, the advantages should be fairly obvious. as i said in the original post this knot combines all the advantages of both the parent knots and very few of the disadvantages. the extra time it takes to tie should be regarded as a strength of this knot as it allows us to assess the whole rigging set-up before commiting to the final cut. ....

Tom's direct question was Why use a Timber H. vs. a Bowline Noose,
something preceding the issue of "Timbowline" loopknot.
As I see it, the advantage of the TH is very easy untying, and perhaps
also not having the material of the knot bulking into some abrasion
against a surface (i.e., one has just the dogged tail & wrap protruding
vs. the knot of the (Running) Bwl to bump into something on the ground).
The advantage of either the hitch or noose over TmBwl is that they tend
to draw up more snug to the object and so inhibit slippage along it,
as opposed to the loopknot. In short, what TmBwl offers is just some
way to secure a long tail. How much advantage that is can be seen in
the demand for an end-securing structure--not much, I sense.
This topic of course led me to muse over some other adornments to
either knot. I've previously recommended that one consider tying the
TH with a full turn around the mainline, which will give some friction
hitch-like gripping of the mainline, and enable the hitch to be set up
more snug to the object, thus 1) preventing loosening (easily) and
2) making a kinder-gentler bending of the mainline at that point
under load--and 3) make the end more securely held (recall LuvNik's
shocking experience of dropping a load onto a TH which came undone
and left his clients (fortunately) in awe of his dramatic load-landing
skills (while he & helper were messing their pants
) ! The full turn
should reduce the force upon the end.
As for my late-night musing, one could tie the TH, then pull the bight
end a bit away from the mainline, and cast a Half-Hitch in that line
around the bight end (forming a sort of Halbmastwurf/Munter'sH./
Crossing Knot structure), and by drawing on bight tip snug up one's
tie to the object!? Effectively, you have a loopknot, but one in which
the encompassing eye can be set pretty snug. YMMV depending
upon rope. I've not played around with this in many materials,
but that's why there's TreeSpyder. (-; (The rope in the TmBwl image
looks to be of an ornery stiffness, not conducive to late-night musings,
or to round turns on the mainline for the TH!)
