The Megabass-Metal Edge uses a rolling barrel on its front hooks to assure the action of the Lipless Vib is not affected by the size of the hooks. It also increases the hook up rates! The Metal Edge creates a high-pitched vibration upon retrieval and attracts fish from deeper regions of the water body. The Megabass Metal Edge could be worked simply with a steady retrieve due to its ability to create a high pitch vibration. Lifting the rod occasionally to cover larger regions in the water is a method many anglers prefer.
