I have used a knot that my grandfather taught me when I was just a kid. It's like an improved clinch, but slightly different. I take the line through, loop it and hold it against the other line...then wrap the tail end of the loop around both lines six times, back through the loop and cinch. I have never had this knot to break. I have actually pulled out snagged 4/O hooks and straightened them flat! I always used it on braid, and it is unbreakable! IMO
