The Streamline Cosmic Neutron Runway is Streamline's first midrange, a heavily overstable disc built to hold a straight line when the wind is doing its best to knock it off course.

Flight Numbers: 5 / 4 / 0 / 3.5

Neutron is a premium, translucent plastic, grippy and durable, and the Cosmic Neutron run adds a swirled shimmer on top of the base color. The beaded rim gives it a firmer lip than most midranges, which helps it hold overstable lines instead of rolling off them.

Power throwers can put full effort into it and it stays accurate, holding a straight line with a strong finishing fade even in heavy wind. It offers more glide than the MVP Deflector thanks to a less aggressive fade at the end of the flight, and it fits neatly into the gap between an Entropy and a Motion for players who bag both. The low profile, flat top, and comfortable rim make it reliable on both forehand and backhand hyzer shots you want to hold, not turn.

Good for intermediate and advanced players who need a midrange that will not fold in the wind, and forehand throwers especially like how predictably it fades back at the end.

Need something that laughs off wind? This is it. Want a similar overstable feel from another brand? The Discraft ESP Buzzz is a more neutral point of comparison, and the Axiom Neutron Hex is a good next step down in stability. Browse the rest of our overstable midranges.
