I use a simple plastic single tail 6 inch "curly tail" and a 4-6 ounce lead jighead. Best colors seem to be purple, amber and black. I think the key is the scent. I use the scent from Halibut.net or any Halibut/Bottomfish scent.
These fish are pigs and will eat anything though, so empty your tackle box before spending alot on new lures.
Good luck-
