Knot strength can be tested in a lab. But the best knot is probably the one that you are proficient in! There are "operator" variables...right knot for the application, twisted line, not wetting line, cinching down too hard/not hard enough, or not noticing/checking line for nicks/smoothness. I don't know. It's just my opinion. Palomar, improved cinch, uni. I've used them all without problem. But kudos for wanting to "improve your game." I guess I'm not much help.
