I'm looking for an adjustable loop that won't slip--any ideas?

[Ruby]

   Will anyone of the gentlemen that had suggested those two loops EVER tie and try the Pretzel loop ?  Noope ! Will they ever "see" that it is more secure, more stable/balanced, more simple, more clever, more versatile knot ? NEVER ! 
   Knot tyers are those who tie their own knots - and ignore everything else... ( However, this is probably the case with artists, in general ? )

because you didn't try best to sell it?

there seems to be no post titled "Pretzel loop".

searched "Pretzel loop", the first post is :
A tying method of the Pretzel "Eskimo" - like loop.

is it?

   You should use the "Advanced Search", in this Forum s Search engine, or in Google s.
   Search for the words "Pretzel loop". You would find many posts referring to this knot... Then, going backwards in time, you will find the original post.

Hi All,
         I have this convoluted wan't slip adjustable here, can support heavy load and easy to readjust loop.

I think it is neat knot. It is easy to loosen and untie, when it is not under load. It is post-eye-tiable. It is also tiable-in-the-bend, if you use slipped loop in the working end.

I made a short video about this knot:

Though I am not aware of any special name for the knot, but yes, it is convoluted. It is easier to untie than Pretzel loop in my experience.
