Let me suggest one more. thaifishingguide.com. A couple of years ago, I posted a similar question, but mainly for higher weight mono lines. Someone pointed out this site, and the Centauri knot. If you are above 20# mono, use the Centauri. It is simple to tie, and you can do it on a pitching boat, and it works great. I tested this and other knots on a tensile strength testing machine.
