THIS DISC IS LIGHTLY USED BUT IN GOOD CONDITION. MOLD FB19. This is part of a sweet Frisbee Fastback collection from various different events and promotions. The Fastback is a uniquely shaped flying disc that is easy to throw and catch. It's also the most used disc for the "Self Caught Flight" competitive event. Self Caught Flight has two components. The "maximum time aloft (MTA) component and the "throw run and catch (TRC)" component. Competition is sometimes held with only one portion of the Self Caught Flight set. Players are very particular about what mold (ex. FB6, FB3, FB1...) they like to throw the event with. More generally the Fastback Frisbee is used in the Frisbee Dogl world as it the most popular shape of dogs to catch. The low profile makes it easier for dogs as well as humans to catch. Most of these discs show some signs of storage wear but are in excellent condition.
