SHADING-X, a masterpiece of finesse shad that has overcome many tough tournament scenes, has been further updated. The ``SHADING-X R'' series has been fine-tuned using the latest engineering to help you win in even tougher situations. The center of gravity of the main weight of the internally installed "TRIANGLE・COUNTER・BALANCING" system (PAT.) has been moved. We have refined the long castability that enables long-distance flight with a bait finesse rod even in strong winds. Furthermore, the ultra-thin body has a wide reclining position and strong vibrations. The responsive "Ultra High Pitch" action tuning brings a new dimension to the feeding element, highlighting the edge of the action. In addition, the "movable back mount weight" placed on the back, which intentionally follows part of the internal structure of the original, has a high center of gravity that moves on the back when twitching, and a low center of gravity that moves on the new lower layer. By dramatically changing the center of gravity of the counter, the behavior of the ultra-thin shad body is changed boldly and irregularly, creating a ``bite'' effect. When the action starts, it immediately starts swimming with a forward leaning position, and in the ultra dead slow retrieve during low water temperatures, live action is generated with just a slight tension on the line. Furthermore, during high-speed retrieval, it switches to a "high pitch vibration" action to induce feeding bites. The new engineering enclosed in this small and too thin delicate shad body is like a precision machine. The SHADING-X R series is a special item for pure competitive use, and is recommended for use in tough conditions where you don't want to give up on the game.
