Just got off a trip where guys with 3 foot leaders were getting chewed off.. see the pic i just added.
4-4.5 feet is the length you want
2 0r 300lb Jinkai Fully Rigged crimped Leaders.
Rigged for West Coast Bluefin jigging
with the following:
Owner 450lb Solid Rings
Owner 300lb swivels
Jinkai 200 mono
Jinkai SG crimps (crimped with a Jinkai SC3 crimper)
4.5 foot leader
Chaffing tubing
400lb split ring with each order
I have caught 100s of bluefin both commercially and sport
I have seem many tackle failures, you dont want to be that guy.
Dont wait until your trip, know your crimper!
