Use to connect braided leader butt to fly line with either permanent monofilament loop or braided loop connector; or to connect smaller end of braided leader butt to monofilament leader tippet with the loop in butt end.
There is a right way and a wrong way to connect loops. Below we describe the method for attaching the fly line loop to the leader butt loop; the same technique applies to attaching the braided leader butt to the monofilament leader tippet.
Step 1:
Pass the end of the fly line loop through the larger end of the leader butt loop.
Loop to Loop Knot Tying - Step 1
Step 2:
Then pass the small end of the leader butt section through the fly line loop.
Loop to Loop Knot Tying - Step 2
Step 3:
Tighten by pulling in opposite directions. You can disconnect the loops by pushing them toward each other and reversing the process. The correct loop-to-loop connection looks like a square knot when complete.
Loop to Loop Knot Tying - Step 3
Step 4:
Incorrect loop-to-loop connection. Attaching the loops this way weakens the connection considerably.
