The retooled Mystic disc from Gateway Disc Sports was PDGA Approved on 5-14-2013.
"We've retooled the Mystic disc top so that its easier to throw straight and land flat at a wider range of speeds. This large diameter Mid-range is faster than most discs in its class and has a really long glide. The inside rim has the larger radius at the flight plate which allows for a smooth and constant release with both the fan and power grip." - Gateway Disc Sports
