MegaStrike Evolution Jigs (Lead Free) feature MegaStrike’s Advanced Skirt Forward Technology and their virtually invisible Fluorocarbon Weed Guard. Evolution is the only jig to also have MegaStrike’s patent pending flaring disk and skid plate. These qualities allow the Evolution lead free jig to respond to every movement of the rod tip. The Evolution Jig will also continue to stay in an upright crawfish defense stature.
