The Atom is a straight flyer with enormous potential off the tee and for long approaches. Right off the shelf, the Atom has a general stability much like the Proxy, with just a bit more fade. Over time the Atom will wear in to an extremely straight and floaty putter. Like the Proxy, the Atom is based on the Envy core with an all-new 10mm overmolded wing design. 3/3/0/1 Electron Soft is MVP's mid-grade plastic, but with more flex and surface grip. While it is not a very durable plastic, it is liked for putters if you like great grip and flexible discs.
