Juro I hope those tests are right but my experience is they will fight to the death UNLESS you really put the wood to them when it's time to go vertical.
We try to keep our drags screwed down at all times. This way the fish hook themselves when they hit the reel and the heavy drag wears them down fast on the inital run. Less lifting/better release/more time to go catch some more.
I wonder how many people fishing for them actually have a federal permit. We have seen so many guys pull up and say "are those bonito?" while they are casting into them.
I got pretty ripped last saturday watching a charter captain gaff a fish at boatside for his sports.
