I've been using a little different way to tie an eggloop lately. I put the line through the eye and make a loop that lays on the shank, then wrap the line and shank by passing the loop over the end of the hook about ten times. This all gets pulled tight and snugged up to the eye and then both ends are cut off close to the knot. This is just a bumper knot on the hook. Now repeat the same knot below the bumper and you are done. The advantages are ,IMHO, it is easy to tie,you can tie a bunch of hooks with the bumper knot and the tie an eggloop in just a few seconds when you need one, you can re-tie a hook without cutting the leader off the swivel , you don't have too pull the whole leader back through the knot to tighten it up,this can score the line . It also eliminates a weak part of a regular eggloop, and that is where the line is bent back around the front of the eye to start the first wraps. If the leader is going to be used for cutplug or spinner herring, I leave a whisker on the bumper knot that sticks out through the eye of the forward hook. This helps to keep the towing hook from pulling through the herring. I've caught many fish with this knot and haven't had a knot failure yet.
Geez,I'm having a hard time swallowing that one mainline knot lasting all season,well maybe the knot, but what about the line getting chaffed on the landing net or strecthed from pulling off snags or all the other things that happen. Maybe they only happen to me.
