caught my 70# thresher with this setup.. 40# spectra. 7'8" 15-30# inshore rod. took an hour and a half outside of NPH.
i heard the best chances for threshers up in the OC are NPH, near the long beach breakwall, and in front of Seal Beach Peir. i ear the canyons of NPH hold larger ones. outside of NPH, the breakwall and seal beach hold smaller teenage T's
