- Experience explosive action with the Quality Cajun Thunder Popping Corks. These corks feature brass and magnum plastic beads that generate an attention-grabbing splashing and clicking sound to draw in fish from a distant. It's the perfect combination for Rockfish, Redfish, Cobia, Trout, and more when used with a 24-30" leader, a 3/8 oz or 1/2 oz HHCB shad head, or shad w/skirt and a plastic bait.
