Perfection Loop
I use this knot when I need one in which the mono comes straight out of the knot. It’s the knot used on the butt end of the leader when making a loop to loop connection.
It is one complicated looking knot, but in reality, it is very fast and simple to tie if one keeps in mind: wrap, wrap, wrap, first through second. The key is getting the first loop (wrap) correct. Study the photos carefully and try it with a chunk of 3/16” rope to get the sequence clearly in mind before trying it in mono.
To adjust the size of the loop after the knot is formed, but before it comes tight, gently push the loop back into the knot and gently pull both the long end and short end of the material to carefully draw out the excess material. I like a loop about 5/8 inch long. Remember to pull on the loop and the long end of the material, only, when tightening the knot. Remember, too, to lubricate the knot with a little saliva before you draw it fully tight.

Lubricate the knot with a little saliva (not necessary on the ropes!), pull only the long end and the loop. clip the short end as tight as possible.
