Shrimp go Backwards, so Marker 54 Popping Cork shrimp go backwards. The Patent Pending design has the exact motion of a fleeing shrimp but in Hard Plastic. A hard plastic flex tail moves identically to that of a live fleeing shrimp, the Hard Plastic body is perfectly weighted to get the same tilt a live shrimp takes when fleeing. The result is a lure that has the same motion and look of a live shrimp... Ask yourself has a trout ever seen a shrimp swim forward?
