I make a few shrimp tails, just from a lurecraft open pour mold. They work and for the price of those molds you can get a couple and make quite a few baits in a short period of time. Caught a few flounder, reds, ladyfish, and bluefish on them. For the price of a pack of gulps you can buy a 4 cavity mold. Im certainly no saltwater fisherman but I do cast a lure around occasionally when I'm sheepshead fishing and these work fine for me.
