The Swimming Senko brings a whole new dimension to Senko fishing. When rigged weightless, the Swimming Senko falls horizontally with a seductive side to side tail action, the tail action of the swimming senko has more vibration and movement than its brother, which can be extremely productive in stained water situations. The subtleness of the original Senko is still prevalent, but the Swimming Senko has more kick in the tail section. The Swimming Senko also works great when pitched or flipped when rigged Texas-rigged. The Yamamoto Swimming Senko is another deadly version of a proven winner. 7 per pack.
