The ringed body style allows a worm to project the appearance of a fat body, as the outer diameter of the rings defines the lure's appearance, while the substantially smaller diameter of the worm's core allows flexibility impossible to attain in a worm as fat as the worm appears to be. But traditionally, worms with a ringed body style have been limited in their rigging versatility by the narrow diameter of the body core. Start poking hooks and jigheads into and through that small diameter core, and you end up with worms that tear or simply refuse to stay rigged the way they are supposed to.
