Great effort if you pick up a Jew, you'd have much better shot with bait even if you collect it yourself eg worms, pippies etc. For salmon, metal lures I found are better but there's no doubt they take plastics I've caught them on the 5" gulp jerkshad as for flathead they will take almost any plastic. Basically don't rule out bait especially on the beach it's no trouble setting up a bait then leaving it while you do your own thing on the beach but if you dont plastics should get you some salmon and flatty, fast retrieve for salmon, keep it on the bottom for flathead and Jews.
