Shimano has engineered the next generation of TC4 Construction. This new construction uses a high carbon butt section fused together with a TC4 tip section. This new blank design gives you the pulling power of TC4 but with less weight and increased sensitivity. You will also notice a much faster recovery rate, which will increase the jigging action and subdue fish faster.
