So John sounds like you are giving up fishing for bluefin. Do not want to hurt the poor fishes. If you feel that strongly about it seems a little hypocritical to fish for them at all, especially with an intent to release. Most of those 14 were probably on for minutes and over a long period of time. A couple years I am told. A decent charter captain will hook that many in a day.
See no difference with this than guys using light spinning tackle or 14wts for big bluefin. End result about the same and we all make our own choices.
