This. Mepps/In-line spinners are the most effective and versatile lure ever made. Most of the responses are for bass fishing, but in-line spinners catch multiple species in every body of water on earth. They are they only lure I know that catch fish in a creek/stream, river, pond, lake, inlet, estuary and the d**n ocean. Not known for big fish, but something about this basic spinner somehow out produces everything else.
If you are only talking bass fishing, then a T-Rig worm is my guess.
