Trolling for Halibut in SF Bay with dead bait: Herring, Sardine, or anchovy ?

Do you find one better then the other ?

Do you ever user flashers, if so, do you see an increase in catch ?

Thanks

i always use a flasher...mostly anchovies, though i occasionally use small herring.  My catch rate is pretty good, but i don't swap it up enough to be able to judge between them
