The YUMbrella Double-Up is a 2-wire iteration of the Bait School Technology phenomenon. Rig it with any two lures to see what the fish are biting that day or to catch two at a time. Identical baits will run side-by-side and different baits will run in a vertical fashion. Many anglers have began using the Double Up Rig for topwater buzz frogs as it creates a presentation that imitates a school or shad or a group of tadpoles as they carelessly swim atop the water's surface. The applications of two lures are really just limited by your imagination.
