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 F Model S has a stable flight and is ready to navigate any fairway with pinpoint accuracy and incredible control. This disc will be perfect for learning how to throw hyzerflip shots that fly straight as an arrow. Thrown hard with a slight hyzer angle, the disc will pop up to flat and ride straight with a mild fade. Players can also get a slight turn by throwing it flat. Just pick your line and hit the target. F Model discs are a great introduction into "drivers". They're made for controlled, accurate shots at a long distance and have a smaller rim for a comfortable grip.
