The Atom is a straight-stable putt and approach disc. The Atom is a straight flyer with enormous potential off the tee and on long approaches. Right off the shelf, the Atom has a neutral stability with just a bit of fade. In premium GYRO® plastics the Atom will retain its neutral stability indefinitely. In Electron baseline plastic the Atom will wear into an extremely straight and floaty putter, with extra tactile feedback inside the circle or in adverse weather. 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. MVP Proton features all black GYRO rims.
