I like mullet live, fresh dead or frozen, although recently I have been catching whiting, croaker and pinfish on a lighter rod and small hook tipped with a little frozen shrimp, then use them as either live bait if small enough or as fresh cut bait.
To my surprise, on the last time out a few weeks ago I caught a number of almost legal flounder on cut croaker, and here I thought flounder only went after live bait.
