The Yamamoto Ned Senko is the exact same shape as the 3"; fat Senko but is built utilizing the ";Mega Floater Formula"; to make this bait stand up on a Ned head. The size is perfect. The shape is perfect and the formula is perfect for Ned rigging. While the original Senko is great for a lot of applications, it isn't for Ned rigging. The bait is designed to have the same feel and texture of the time tested Senko, but it floats making it stand up and be more visible when dancing around the bottom of your favorite fishing hole.
