The Streamline Proton Jet (Reaper Edition) carries the shop's flame logo on the understable Jet mold, cast in Proton, a step down from Neutron in stiffness. The Jet works as a big turnover disc, a hyzer flip machine, or a straight flying driver, depending on how much snap you put behind it.

Flight Numbers: 11 / 5 / -3 / 2

Proton feels softer and grippier than Neutron, with more give in the flight plate, and it tends to fly a bit more stable than the stamped numbers suggest until it has a season of throws on it. It handles forehand torque well when released cleanly, and once it beats in the turn opens closer to the full -3 on the label.

Thrown flat with real snap it turns some before fighting back to a decent fade rather than burning all the way over, and advanced arms have pushed it near 370 feet on a clean release. Into a headwind it holds up better than a typical understable driver, riding out a slight turn instead of flipping hard, a solid tailwind disc once you learn its flight.

Good for an intermediate player who wants a Jet that plays more stable while it breaks in, and for a forehand thrower who needs a disc that takes torque without flipping immediately. Best shot: a tailwind drive where the extra turn works with the wind, not against it.

Want this same mold without the flame stamp? The Streamline Proton Jet flies identically at a lower price. Prefer the grippier plastic that stays truer to the printed numbers? The Streamline Neutron Jet holds its flight longer before beating in. Browse our understable distance drivers.
