Designed by B.A.S.S. and FLW touring Pro Jim Moynagh, the Rock Jig -Tournament Football Head is designed to help it travel through rocks and gravel, over ledges and through other hard bottom areas without getting hung-up. The Rock Jig is an updated version of Jim’s “Roller” football jig that Jim helped introduce in the mid-1990s. The new Terrain Tread on the underside of the jig actually grips the bottom allows you to feel the bottom composition better than ever before. We build the Rock Jig on a heavy, black-nickel, Mustad UltraPoint hook.
