This knot couldn’t be any simpler, it’s quick and reliable. However the loop formed is always slightly offset from the main line. No problem for bottom fishing, but for trolling with light tackle we would use either a Leader loop knot or a Perfection loop knot. For heavy leaders use alloy or copper crimping sleeve swaged with a quality swaging tool. Double over 6 – 8 inches of line. Make an overhand knot, make another. Lubricate with saliva and pull up tight.
