Hey albie -
You are talking true albacore pacific offshore, correct? I would agree with Sean, an 8wt might be a little light to get those birdfins up from the depths especially if the captain is not going to stop the engine for each hookup. Maybe even a 12
Don't think there's too much C&R in true albacore fishing... there wouldn't for me up to the legal limit. That is some of the best stuff I've eaten from the sea, whether served tataki style (original Japanese seared / sushi middle with light ponzu sauce and chopped onion wafer thin), on the grill, or even home-canned with a little olive oil, cider vinegar and pickling spice in mason jars. It takes months to be able to stand tin can tuna after eating this stuff.
I don't think they are endangered, if so I would lay off and probably try to solve the chinook on the fly enigma closer to shore or something.
So do tell what is your plan for pursuit?
