If you want to take a slow attack in aging and mebering, it is a common practice to lighten the JH, but the disadvantages are that the flight distance is reduced and it is difficult to feel the presence of the rig. As a way to eliminate such disadvantages, it was developed so that the worm itself can be dealt with by giving it a sense of resistance. The characteristic splash catches water and increases resistance, so even if you use JH of the same size, you can make it fall slower than a normal worm, and it will be easier to keep the range. In addition, the presence of the lightweight rig is easy to understand, so it is easy to operate.
