SHADING-X, a masterpiece of finesse shad that has overcome many tough tournament scenes, has been further updated. In order to win in even tougher scenes, the "SHADING-X R" series has been fine-tuned using the latest engineering. The "TRIANGLE, COUNTER, BALANCING" system (PAT.) installed inside The center of gravity has been shifted. The long-castability has been honed to enable long-distance flight with bait finesse rods even in strong winds. In addition, the ultra-thin body has enhanced the wide fall and violent vibration. Tuning to responsive "ultra-high-pitch" action that highlights the edge of the action brings a new level of feeding element. In addition, the "movable back mount weight" placed on the back, which deliberately follows part of the original internal structure, boldly and irregularly changes the behavior of the ultra-thin shad body by dramatically changing the various counter center of gravity by the two centers of gravity that move the back and the low center of gravity that moves the new lower layer when tweeting. When the action starts, it immediately swims out in a forward leaning position, and in the ultra-dead slow retrieve during low water temperatures, live action occurs with just a slight stretch of the line. In addition, high-speed retrieve switches to the "high-pitch vibrate" action to trigger a feeding bite. The new engineering enclosed in this small, too thin and delicate shad body is like a precision machine. The "SHADING-X R" series, which is recommended for use in tough conditions where you don't want to give up the game, is a special item for pure competitive youth.
