"RUNNING KNOT"------This is my favorite knot that I have used for 50 years. It has NEVER FAILED me. It is FAST TO TIE and EASY TO TIE. It is SIMPLE TO TIE. Try it and tell me what you think. I use it for mainly dry flies, but also for sea run cutthroat. I don't normally use it for salmon fishing, but go to a clinch knot. What is also great about this knot is, when the fish are rising all over hell, and you are in a hurry to change flies, it's a godsend... I should point out that I cinch the knot first, pull it OVER in front of the eye, then slip it down TO the eye, tightening both pieces of leader material.
