The Koya Lures 9" Tube is as the name states except that it carries the punch of what you would expect from a Koya Lure. Top of the line tube bait with a very slight taper towards the nose - almost completely flat-backed with a slanted nose. These heads stick pretty close to the top of the water and swim erratic to imitate a baitfish feeding at the surface. Creates a lot of commotion that lure fish up to bite. Great on Billfish especially.
