These spinnerbaits are one of the most durable and true running blades on the market. Catch fish after fish and this blade just keeps on performing. The 3/8 oz. use a .32 wire, 1/2 oz. use a .35 wire, while the 3/4 and 1 oz. use a heavier .38 wire. We use a ball bearing swivel that allows the back blade to turn with the slowest movement. Always a 4/0 Gamakatsu sharp hook.
