Champion Line is produced with a hi-tech plastic that provides outstanding performance and durability. Champion discs are distinguished by a clear or pearlescent plastic. Champion Line discs retain original flight characteristics for an extended period of time. Whether used in heavily wooded situations, or on extremely rugged courses, Champion Line plastic will continue to perform predictably and avoid damage better than any other plastic. Originally designed for professional players, Champion Line discs are usually more stable than the same model in Pro, R-Pro or DX.
