The Pro Ultra Sonic Disc shape is optimized to add the desired effect, but still very easy to lift of the water due to the venting holes, while maintain the capability to create a vortex behind the disc, allowing soft modern materials to swim freely instead of collapsing in hard current.

This is the future of modern fly design without a doubt!!
