I'm not far from Wrightsville.

Other than the obvious normal salty stuff (clousers, decievers, etc...) I would definitely bring along a few size 6 crab patterns in a dark brown or an olive. Suckers are everywhere around here in the marsh, and I recently cleaned a redfish that had 3 of them digesting in his gut. This is probably the go-to sightfishing fly in the marsh over here. Look for high-tide, find the fish with his nose down in the grass, and hit him on the head with that crab.
