Caught em off of the Mendocino Ridge in the mid '80's (pre and post El Nino years) while fishing albacore (commercial) along with 70lb Yellow Fin Tuna's.
There was a recent post on another board that a jumbo size Bluefin was also caught out of Crescent City.
There have also been reports of reels stripped of line by "Something big and fast" up here too. Could be big Albacore, Blue Fin Tuna, Swordies or even Opah...Or crap worn out drags
