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.
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.
