What is the strongest knot for fishing jigs and texas style worms?  I always tie Palomar knots on 12 lb test line when fishing a baitcaster.  I hate piercing fish with worthless jewelry. Has anyone tried the commercial line glues for knots?  

Palomar is the simplest & strongest knot you can tie  

Palomar . Never used glue , no need.

If you are concerned with "piercing fish with worthless jewelry" maybe you should use a heavier line and learn to tie knots correctly. Glue won't make up for a poor knot.

Tie the palomar and set your drag correctly.

Palomar all the way.

Later,

As the others have said, tie the palomar and make sure your drag is set properly! If you're fishing heavy cover you may want to consider moving up to a heaiver line also.

The only knot, that I know of, that has a stronger knot strength than the palomar is the jansik special. It takes longer to tie and I use it for musky fishing only.

I've seen anglers on TV shows using what they called a loop knot. They say it illiminates the use of a split ring and allows the lure to act natural. Does anyone use this knot and can someone show me how to tie it?
