The Streamline Boost in Neutron SL is an overstable distance driver with a fast, hard finish. It flies close to a Firebird in how much it fights a power throw.

Flight Numbers: 9.5 / 4 / 0 / 2.5

Neutron is the same premium family used across MVP, Axiom, and Streamline, and the Streamline plastic feels great in the hand. Overstable molds like the Boost should stay overstable for a long time as they wear.

It is not as overstable as a Flare but more so than a Thunderbird or a Tesla. Thrown flat with power it holds its line, then fades hard left at the end. On a hyzer it comes back quickly. It behaves like a faster Firebird and carries less distance than the 9.5 speed implies. That makes it a wind disc, a forehand flex shot, and a dependable finish on a hyzer line.

Built for intermediate and advanced arms. A slower arm will not get it up to speed and will see it dive early.

Want something that flies further with a little less fade? Try the Streamline Neutron Jet. Need a bit more turn in the same brand? The Streamline Neutron Flare is the next step, and the Innova Star Firebird is the classic comparison if you want a proven flex driver. More in the distance drivers.

Speed 9.5, glide 4, turn 0, fade 2.5. Diameter 21.2 cm, rim width 2.1 cm, max weight 175 g.
