I think that San Diego Jam is the basically the same as the sixteen-twenty knot (also known as Eugene bend,16-20,pitzen). Same background as Jay, my dad taught me this knot over 50 years ago and I use it exclusively for all lures and all lines. I never knew the name until last year. You always know if you tied it right because it pops as you cinch in down. Don't know how smart it is but after you tie this knot for a while you discover that you can hold the loop in one hand and the tag end in the other hand and swing the lure in looping circles around the line for the wraps. Then you simply stick the tag in the loop, wet and cinch it down. Pretty fast and it has been advertised to be a 100% knot (does not weaken the line).

Thanks!

Palomar, simple and strong.

I used what you call the "sixteen-twenty" knot for many years because it is so easy & quick to tie - but we always called it the hangman's noose knot. I don't use that knot anymore because I figured out that the "POP" you hear and feel is when the line gets abused and looses strength. I can't imagine that someone feels it is a 100% knot. I've only tied the San Diego Jam knot a couple of times, but I did not feel any "pop" when I tightened it down, and looking at how the knot works as it tightens I would not think that it should "pop".

Palomar for plastics and flurocarbon. Trilene for mono and moving baits.

It's gotta be a smart way of doing it, 'cause I do the same thing.

Been using the Uni-knot with no problems since I saw it in Dave Hawk's book in the 60's. Not sure he called it a Uni-Knot, but I like it.

Now everyone is thing who the H is Dave Hawk.

I use the 16/20 knot for mono and braid. I have never heard any pop when I cinch it down. Maybe it doesn't pop with Pline. I use it because it is fast, esay, strong, and I can tie it with gloves on in the winter.

I have not used the "Hangman's" with anything but mono (I no longer use mono) so I don't know whether it pops with co-poly, FC, or braid. I've been using the Palomar mostly. With the Hangman, you have to pull the knot fairly tight to get it to pop - and I think when it pops it is damaging the line/knot. I do not trust that knot at all & will never use it again. IMHO

here's a great link

i like the way the overhand know is "doubled" here

Palomar is a good one for sure. When I tie the Palomar (all thumbs that I am), I almost always wind up cutting off (wasting?) a very long tag end - several inches. I'm mostly using braid with a P-Line co-poly leader these days so chopping off the line each time I re-tie forces me to replace the leader more often than I like. I was thinking that maybe the San Diego Jam knot would waste less line.
But since most of us probably don't remove enough line each day to never have abraded areas near the baits, maybe cutting off those inches of line is not a bad thing.
No perfect solutions I guess.

Be sure to wet the line and re-tie often. No matter the knot its only as strong as the line! Berkley and palomar for me though!

I gotta go with the palomar as well. It's easy to tie and when used with good line it is hard to beat.

I'm certainly no expert but this guy apparently is and test knots for strength. He is a fly fisherman and he says the 16-20 does not work well with heavier line but I think I get the same knot up to the 17 pound test. Here's what he says about the 16-20:

Strength:
"the 16-20 trounced every other knot. The 16-20 bested the Trilene knot about 90 percent of the time. It beat the clinch knot every single time, and almost always beat the Palomar knot. Like the nonslip loop, it sometimes achieves 100 percent efficiency."

Tying it:
�Give the tag end another gentle tug to make sure that the wraps are compact (but still not too tight), and then pull hard on the standing line. And I mean hard, because something interesting happens when you pull with enough force. You will feel, and perhaps hear, a click as the knot seats. There's no mistaking the click � you will feel a jolt in the line. When you feel and hear that pop, the knot is seated and finished. You will also notice that the tag end comes out of the front of the knot nearly parallel with the standing line. That's your other indicator that the knot has seated properly. You must feel the click and see the tag end exit the front of the knot almost parallel with the standing line. If either of those does not happen, cut the knot and tie another. �
