plugchunker, I've been using live shrimp under an Alameda Rattler cork and then switch to a Glow or Pink Rockport Rattler jig rigged with a 3" pearl Gulp! shrimp when I run out of the live shrimp. I invented the Rockport Rattler jigs back in 2003 and you can find them in your local Academy or tackle shop.
I catch a better variety of fish using live shrimp vs. croaker and a Rockport Rattler jig rigged with the 3" Gulp! shrimp will do the same.
When I am after bigger trout, I will use the 5" Plum/Chartreuse SW Bass Assassin rigged on a Chartreuse/RedEye Rockport Rattler jig.
