Innova does some crazy stuff sometimes. Just read on the PDGA forum that the Coyote has been retooled to be more stable. The original flight numbers on the Coyote were 4,5,-1,1. The new numbers are 4,5,0,1. And the Mako which just came out is 4,5,0,0. Seem crazy to make two discs so similiar and retool one of them to make it almost exactly the same. Prediction: The Mako will be retooled. New numbers will be 4,5,1,1.
