The Insanity is best described as a worn-in MVP Inertia, with slightly more high-speed turn and a diminished fade. For average power throwers, the Insanity will be remarkably straight, while high power throwers can execute precise flip and turnover lines with ease. The Insanity is a fan favorite in the Axiom line up. Now in MVP's amazing glow plastic, this disc can carve the fairways day AND night.
