Stu Foxall's latest creation is a tube fly utilizing the Pro Sportfisher Ultra Sonic Cones. These cones are made of brass and are slotted. The Ultra Sonic Cone adds some weight to the fly, but is still very easy to lift out of the water due to the venting holes, while maintaining the capability to create a vortex behind the disc, allowing soft materials to swim freely instead of collapsing in hard current.
