The Ace Line DuraFlex M Model US midrange is a reliable, understable midrange for any bag, molded in DuraFlex plastic. It's built for players of any skill level, and it's at its best on dead-straight lines and beautiful turnovers. Ace Line discs are made by Prodigy, and this DuraFlex run is a dependable pick for your bag. Discs in this listing weigh 177-180g.

DuraFlex Plastic

DuraFlex is Ace Line's premium blend, durable enough to stand up to time and the elements while still giving excellent grip. Ace Line says it stays nice and grippy from the very first flight to long after the disc has slowly broken in.

The Mold

Thrown hard on a flat angle, the M Model US rides gently to the right before a mild finish. It also holds a turnover angle for a long time before finishing flat. Work it at different angles and you can get dead-straight flights and beautiful turnovers from the same disc. With a slightly larger diameter than drivers, M Model discs are designed for control and are a great tool for learning different flights on drives and approaches.

Stability

The M Model US is understable. Understable discs turn away from your throwing arm at speed, making turnovers and hyzer-flips easier and helping lower-power players fly straight. For right-hand backhand (RHBH) throwers, it tends to drift right during the fastest part of its flight, then shows a gentle fade back to the left at the end. Left-hand backhand (LHBH) throwers will see the mirror image, drifting left early and fading right at the end. Forehand flights flip that pattern: right-hand forehand (RHFH) follows the LHBH line and left-hand forehand (LHFH) follows the RHBH line. It suits beginners who need help getting straight flights as well as advanced players who want to shape turnovers.

No. The M Model US is understable, rated 4/5/-1/1. Its turn makes it a better fit for turnovers and hyzer-flips than hard fades.

What do the letters in Ace Line disc names mean?

How far does the Ace Line M Model US fly?
