The Boss is a great disc choice for sidearm or backhand throwers. This is a fast stable driver that can handle full power throws and moderate headwinds. Advanced players and sidearm throwers will appreciate the dependable stability. The Boss has a slight high speed turn to help maximize distance with a predictable fade. Not recommended for players who throw less than 300 feet/90 meters. The Champion Boss is endorsed by 2008 World Champion, Dave Feldberg.
