These Pro Soft Sonic Discs from Pro Tube are made from reinforced plastics and are strong, super light and very effective. The venting holes allow water to flow through the disc adding life to soft materials, but more importantly they reduce the amount of energy needed to lift the fly out of the water!
The Pro SoftSonic disc is also great to lift wings and hackles, without damaging the delicate fibers. Turn it around and you have a wobbler like action. Now that is versatility! By far the most popular Pro Tube add-on.
