Champion plastic discs are high quality, durable, and maintain their original flight characteristics for a long time. Champion plastic tends to be more overstable than DX or Star, it's less flexible in the hand than pro plastic and many players like that rigid feel. Innova loves their plastic so much they have named a team after it! It's not just for pros though, players of every skill level can bag some champion plastic. • Firmness suitable for the increased throwing speeds of professional players   • Retains flight characteristics longer than DX or Pro Plastics
