Usage
The Perfection Loop is a fixed loop knot that can be tied in the middle (on the bight) or at the end of a rope or fishing line. Favored by fishermen, it ensures the standing end aligns perfectly with the leader or tippet, creating a streamlined connection. In fly fishing, two Perfection Loops are often joined to form a 'Loop to Loop' connection between the fly line and leader. The Perfection Loop is equally useful with rope and can often replace the common Bowline in various applications. While secure, it can be difficult to untie after tightening.
History
Although most fishermen now refer to it as the Perfection Loop, Ashley originally called it the 'Angler’s Loop' in the Ashley Book of Knots, a name that is less commonly used today.

ABOK
Strength/Reliability
The Perfection Loop is quite secure and jams badly — which is desirable in fishing line. It is also one of the few knots that holds well in bungee cord.
