The Discraft Pro D Avenger SS is a maximum distance driver with a Stability of 0.5 (slightly overstable). Discraft took the best aspects of the Avenger, its speed and glide, and flatted the edge. The result is a golf disc that flies longer and is easier to control. Throw it hard and flat for a slight fade to the right, then watch the Avenger SS keep on gliding through a smooth, gentle finish. It is a great flat flier for Ams. Pros love it for turnovers.
