Loop knots have many uses in fly fishing, and there are probably just as many types of knots as there are uses. While it has other uses, the Perfection Loop is my favorite knot for putting a loop in the butt of a leader. Because the Perfection Loop keeps the leader “in line” with the loop, it allows for more accurate casting. Other loop knots often leave the leader at a slight angle from the loop.
Most commercial leaders already have a Perfection Loop tied in the butt section when you buy them. But if you are thinking of making your own leaders or just need to make a repair in the field, this is a great knot to know. Near the end of the video, you’ll also see how to make a loop to loop connection to attach the leader to the fly line.
