I've been having luck this year on crab patterns, every redfish I've kept has been filled with them. Also there's been a huge hatch off tiny glass minnows, take a few crazy Charlies with you. If you're blind casting I'd go with a gurgler or some other sort of popper. Smaller flies have been the ticket this year. My crabs have been size 4, Charlies size 6 and 8 and gurglers size 6. I've had nothing but refusals on bigger flies. Good luck.
