Bj, I’ve always done good with either larger live shrimp, or live pinfish with their tails trimmed off. I’ve never personally used crab, but I’ve heard it works very well. I’ve also seen and heard alot of guys using cut chunks of ladyfish and chunk mullet. Ive personally caught alot of redfish on gold spoons and paddle tails for artificials, alot of people ask what color. I believe the color of paddle tails used depend on water colors, darker water usually I’ll use darker colored baits. More clear water and lighter colored water I typically used lighter colored paddletails. I feel like You can never really go wrong with white in any situation.
