I like using 4-6oz butterfly jigs. Crippled herring type of a thing. They're easy to fish and work. Second is a large orange or rootbeer worm with a 3-8oz jig head (depending on what weight you need). Herring an live greenling work, but I'll second that it's more fun jigging them up.

I've had the best luck when current is moving. You can find them at slack tide, but not near as common. They're predators waiting in the rocks for something to come by. They'll tend to hang on the down-current side of structure.

I like casting slightly ahead on the drift and pounding the bottom a couple times. It's a dangerous game, but I think the commotion helps bring them out to see what's going on.
