Yamamoto Baits 3.5in Swimming Senko 7 Pack 3.5in Black-Blue. Thanks to the tail the Swim Senko presents a hard-to-resist horizontal action that's more than enough to tempt a lunker to bite. The Swim Senko marries the natural profile and subtleness of the Senko with the vibration and movement of a paddletail swimbait. The result is the perfect amount of subtle shimmy and the perfect amount of kick. Available in 5 sizes ranging from 3.5" to 5" long the Swim Senko is a favorite of anglers everywhere.
