With my old eyes and fumble fingers, I also use the Kreh Non Slip mono knot. An excellent knot and strong - pay attention to the number of wraps around the main line determined by the line strength. My other go to is the Palomar, another very high knot strength, easy to tie. I recently had that knot break on me (a very rare occurrence) and in all fairness it was my fault because I had successfully pulled a jig out of some very bad cover, and had freed my jig from some rock bottoms. I should have retied it but was lazy - my bad. For line to line (such as replacing line tippet) I have been using a double surgeons because it is so easy to tie and a strong knot. You only need to learn a few. How to tie a loop knot, attach a hook to line, and a reliable line to line knot. Practice and be able to tie them well.
