Ace Line Discs come in assorted Colors. ProFlex has a similar look and feel to the 400 Plastic in the Prodigy line, featuring vibrant translucent colors and a reliable grip. ProFlex has less stiffness but will take longer to wear in than DuraFlex. The M Model US is a great fit for any bag because of its reliability. Give it a nice, hard throw on a flat angle and watch it ride gently to the right before having a mild finish. It will also hold a turnover angle for a long time before finishing nice and flat. Work the M Model US at different angles and you can find a dead straight flight and beautiful turnovers in the same disc. It's an easy choice for any skill level. With a slightly larger diameter than drivers, M Model discs are designed for control and provide a great tool for players to learn different disc flights on both drives and approach shots.
