Here's what Prodigy Discs has to say about the M2:    

M2 is an extremely reliable mid range driver, designed to be slightly over stable with incredible consistency and control. The M2 mid range is good for all conditions and flies as well into the wind as it does with the wind. The consistent flight path of this disc makes it a favorite of the top rated players in the world. The M2 features the trademark Easy Release Technology.
