Sometimes a bait does not have to provide much action to catch fish. If you notice how shad swim, they do not wiggle very much so it may be that it is a good visual bait, but the rattle in it may be enough in off colored water to do the job. I think the new sinking Gizz-4 will have a little more wiggle than the shallow running lure. I think the fact they look so much like a shad, makes it a product lure for larger bass, especially if it is worked slow.
