Foodfisher uses the same setup I often use in the surf, though I am fishing much further north. When I fished California, I usually used sand crabs/flees. That was before Gulp Alive sand worms were on the scene. In the rocks, my brother does pretty well with chunks of squid near Irvine. He told me things are a lot slower in the winter.
If I get a chance to fish down there again, I would like to try Gulp Alive 4 inch chartreuse mullet. They are a killer here on flatfish.
