Here's what Prodigy Discs has to say about the MX-3:    

The Prodigy Disc MX-3 is a slightly overstable, beaded midrange that is engineered for high-level controllability and performance, meeting the demands of professionals while providing benefit to varying classes of players.

The MX-3 is designed to be highly resistant to torque, ideal for players who throw with force and need to avoid turnover. Headwinds are no match for the MX-3, with a slightly overstable to straight flight that still offers an impressive amount of glide, especially when thrown on anhyzer and flex lines. Its beaded rim provides a comfortable grip, smooth release, and consistent stability.
