Energofish Flatliner Sinker (coated) The special carp leads for specialists. Over the last couple of years these leads have made their mark on the market. Due to the special construction of these leads, should the line break during the fight, the lead separates from the line, thus not hindering the carp. The grey metallic coating of these leads makes them virtually invisible to the carp and therefore do not scare them away, and their aerodynamic form give them extra casting distance.
