DuraFlex Glow 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. This run also glows in the dark, so it's ready for night rounds and glow leagues.

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.

FAQ

Is the Ace Line M Model US good for beginners?

Yes. Ace Line calls the M Model US an easy choice for any skill level.

Is the Ace Line M Model US overstable?

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's the difference between DuraFlex and ProFlex plastic?

DuraFlex is stiffer and wears in a bit faster. ProFlex is less stiff and translucent, and takes longer to wear in.

What do the letters in Ace Line disc names mean?

The first letter is the disc type (P for putter, M for midrange, F for fairway driver, D for distance driver), and the second part is the stability: S for stable, US for understable, and OS for overstable. So the M Model US is an understable midrange.

The Ace Line DuraFlex Glow M Model S (6/4/-1/3) is the stable version with more fade.

How far does the Ace Line M Model US fly?

With an average arm, expect roughly 260 feet. Distance depends heavily on your power and form, so stronger throwers will go farther and newer players shorter.
