Here's what Prodigy Discs has to say about the D Model Overstable:    

The D Model OS is an overstable distance driver that is power player's dream. Those with more power can throw this disc hard, and it will work to fight out of its slight high-speed turn and finish with a harder fade, thanks to its fast, overstable flight. D Model discs are built for maximum distance and have a sharp nose and slight dome for increased speed and glide. They also feature medium-depth rim to allow a comfortable grip across different hand sizes.

Speed: 13   Glide: 5   Turn: 0   Fade: 4
