Designed to hold up to the constant abuse of trolling and run flat thru the water. The wire is beefed up to .062, clevises are #8 and ride on a nylon spacer to reduce wear, blades are 'double thick' #10s and two weights are spaced evenly in the body so the Trolling Girl runs horizontally and not tail down like most bucktails. This is the ultimate trolling bucktail!!! Oh, and they are an excellent casting bucktail as well. Just don't tell anyone you heard the secret here first!
