Yumbrella Ultralight Flash Mob Wire. Plenty of instances call for a smaller multi-lure rig. The YUMbrella Ultralight is a downsized 5-wire YUMbrella rig. The YUMbrella Ultralight can be fished on any type of equipment and is a terror on largemouth, smallmouth and spotted bass, crappie, white bass and just about any predator fish. The YUMbrella Ultralight is made with the same super-tough stainless steel wire and durable connections as the full-sized model. It doesn’t matter if you’re fishing a stream for smallmouth, a reservoir during the shad spawn, or a pond for crappie, the YUMbrella Ultralight creates the illusion of a small school of baitfish and provokes strikes from even inactive fish.
