Now, the Shaky Rig has grown up. Instead of 1/8- and 1/4-ounce jigheads, or smaller, kick it up a few notches. Try a 5/8- or 3/4-ounce jighead, sometimes round or football style and maybe with a flattened bottom to help the worm stand up. The worm? Instead of a lithe squeaker, go with an 8- or 10-inch brute typically used in summer for punching vegetation or dragging on the bottom.
