I read that Jimmy Houston did extensive tests on knot stength. A knot he developed with a buddy, the Jimmy Houston knot, he claims is 100%. I personally don't tie it. He said about the next best knot is the trilene knot. Usually I tie a palomar. Iaconelli says NEVER USE A PALOMAR with flourocarbon. It burns the line. He suggests an improved clinch. In which case I would use the trilene knot. I like the trilene in that case because it passes the line thru the eye twice like the palomar. Common sense tells you that has to make it stronger. Most importantly, tie your knots carefully. EWG
