Multi-lure rigs exploded during a time of year when baitfish were of substantial size, and through the winter and very early spring anglers caught big largemouth, smallmouth, striped bass and other fish on rigs with 3 ½- to 6-inch swimbaits. Then the spawns came and these bigger offerings often went untouched. Some anglers used it as proof that multi-lure rigs were just what they thought they were – flashes in the pan – gimmicks that already went out of style.

Then a few smaller multi-lure rig versions appeared, and a few anglers gave them a shot, often using smaller 3- and 4-inch grubs instead of the bigger-bodied swimbaits. The results show the learning curve of these rigs is continuing to evolve. These smaller versions with more petite caught plenty of fish, and in fact still are right now.
