The Streamline Range in this Champions Cup stamp features DoubleRam Design's robotic Entomo Unicus artwork on a stable putt and approach disc, and Proton Soft is the plastic this run comes in.

Flight Numbers: 2 / 1 / -0.5 / 0.5

Proton Soft grips well from the first throw and needs almost no break in before it feels right in the hand, softer and more pliable than Streamline's firmer Proton blend. It holds up fine to regular putting practice without cracking, and the low glide rating keeps the flight short and controlled rather than floaty.

Thrown for a putt this disc drops fast with very little glide, which is exactly the point for players who want a putter that stops instead of skipping past the chains. As an approach disc it holds a hyzer line cleanly and resists turning over, so it is useful on tight upshots where you cannot afford extra roll. Torque resistant enough for a big spin release, it works well for advanced players who put a lot of spin on their putt and want the disc to hold that line anyway.
