The Fireball is overstable and wind-resistant like the MVP Motion but has an overall straighter and longer flight profile. The Fireball has a longer forward push during its early stage of fade, where the Motion would have begun a long gradual fade. At the end of its flight, the Fireball will drop later and more abruptly than the Motion. Our original premium plastic blend, Proton is a translucent core material with stunning optical clarity and vibrant colors. Proton has similar durability and slightly more grip than our Neutron plastic. The colorful candy plastic core yields a different aura to each model and especially suits LED-lighted night play. Axiom Proton features vibrant color GYRO rims.
