The Yamamoto 5" Thin Senko is the skinny brother of the original 5" Senko. The slender body of Thin Senko lends itself well to drop shotting and other finesse presentations. It&';s able to differentiates itself from the other trick or slender worms with its characteristic Senko action. It works great with the NED rig and the Neko rig too. If you want to get more life out of your Senko you can use an O ring and tool if you are wacky rigging or Neko rigging.
