Axiom Neutron Insanity, 172g9 5 2 1. 5 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. Whether youre looking for that sweet spot worn disc flight, or youre looking to achieve bigger Inertia lines with less power, give Insanity a shot.
