Tied the San Diego for so many years then about 5 years ago I went all polamar
They both work great

I use the SDJ because it was the first knot that I had been shown and it is easy to tie even in the dark. I have seen some sights that rate knots by their strengths and it usually comes in a close 2nd.

SDJ for most things on fluoro, but sometimes use the improved clinch for lighter lures. Haven't noticed a difference in line breakage between the two.

I use mostly improved clinch for lures, and Alberto knot for braid to flouro.

Doubled Uni knot is great and it's very strong. I still use a Paloma's for my spinning rods without problem bc the drag does all the work and the Palomar is great with dropshot.

Doubled uni is the same as a uni except you double the line up. the doubled uni is a line to lure knot, (not to be confused with a uni to uni splice)

Flouro= San Diego Jam!! I've used this knot in saltwater for many years before utilizing it in bass fishing...

Trilene knot on my copolymer lines,
Shark knot fluorocarbon
palomar on braid.

Shark knot is one I learned from a video from mark zona. Easy to tie and I have never had one break at the knot.

I use a Palomar or fishing fool knot if im tying to someting small like a swivel for a C-rig or tx.rig or drop shot hook.
Double SanDiego Jam for jigs and swim batis.
Alberto knot for joining two lines together, braid to a leader.
Double Uni when joining backing line on my reel to the main line.

Here is a link to the video on the shark knot if anyone is interested.
