17# Mono (approximately 20# break strength)
Roughly 1/2 of the length of 4 strand, twisted mono, and 1/2
of the length is 2 strands of twisted mono, creating a loop at each
end. This system creates a 2-step “tapered leader”, which is perfect for big game; like tarpon, billfish, tuna, etc.
The 4-strand loop is connected to the fly line (loop-to-loop);
and the two strand loop is connected to the bite leader, using a No-Name Knot.
The two-strand loop is the “fuse”, with a breaking strength of about 20 lb. test (not IGFA).
Note: I have used Twisted Leaders for striped bass, tarpon, and redfish,
for over 20 years! I have never had a failure. The tarpon and redfish pictured,
are examples of how effective these leaders are!
