Insanity - Proton
The Insanity is best described as a worn-in MVP Inertia, with a slightly faster spin and decreased fade. For mid-power casters, the Insanity will be noticeably straight, while high-power casters can execute accurate flip and turnover lines with ease. If you're looking for that worn-in disc flight sweet spot, or are looking to get bigger Inertia lines with less power, give the Insanity a shot.
