The Runoff Triple Threat lures are made in both 4 arms and 3 arms. They are durable, made out of stainless steel. These lures can be used with trolling, casting,drifting, or jigging techniques. They come with 150# cross lock swivels so you can put on hooks, plastics, tubes, or jigs. Fishermen can drift the bottom for fluke and free spool one on top for bass and blues at the same time.
