Ace Line: D Model US

Prodigy Discs says this about the ACE Line D Model US:

The D Model US is built for beginners and players with slower arm speeds. With it’s naturally understable flight, the disc will want to turn over and hold before coming out of it to softly glide back toward the ground. The increased glide and soft fade are a perfect combination for players with less power to work on getting the desired flight for maximum distance throws. Players who do have more power can use it for long turnovers and rollers.
