By far squid is the gaurentee producer for rockfish. Literally everytime I dropped down with a strip of squid yesterday I was hooked up. They arent the greatest of fights though. You feel a little hit and set the hook, thats it. You real them up and they are dead with their air bladders sticking out of their mouth.
Lingcod will give you a run for the money. They really fight good all the way up to the top. The best bait for those I believe is live anchovy or sardines if you have them. The more livley the bait, the better. They get all excited and just pounce on it.
