The Ace Line DuraFlex D Model OS distance driver is an overstable distance driver and a power player's dream, molded in DuraFlex plastic. It's built for power players who need a hard, reliable finish, and it's at its best on power drives, headwinds, and hard fades. Ace Line discs are made by Prodigy, and this DuraFlex run is a dependable pick for your bag. Discs in this listing weigh 170-175g.

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

Throw the D Model OS hard and it works to fight out of its slight high-speed turn, finishing with a harder fade thanks to its fast, overstable flight. D Model discs are built for maximum distance, with a sharp nose and slight dome for speed and glide and a medium-depth rim for a comfortable grip across hand sizes.

Stability

The D Model OS is overstable. Overstable discs resist turning over and fade hard at the end, which makes them predictable in wind and at high power. For right-hand backhand (RHBH) throwers, it resists turning over and finishes with a strong, dependable fade to the left. Left-hand backhand (LHBH) throwers will see the mirror image, with that hard fade finishing to the right. Forehand flights flip that pattern: right-hand forehand (RHFH) follows the LHBH line and left-hand forehand (LHFH) follows the RHBH line. It's best suited to intermediate and advanced players, and it's a valuable utility disc for anyone who plays in wind.
