Developed as a special collaboration between Gateway Disc Sports and Foundation Disc Golf, the Cornerstone is a highly controllable, neutral 9-speed fairway driver built to act as a dependable workhorse on the tee. It features a slightly domed top with a relatively sharp parting line and a rim width that feels comfortable in the hand for both backhand and forehand grips. When thrown flat, it provides a beautiful S-curve flight by gently turning over before displaying enough low-speed stability to fight back with a reliable finish. While massive arms can utilize it for long hyzer flips and sweeping distance shots, slower arms will find it to be a straight, highly predictable driver that easily cuts through tight gaps and holds lines without any sudden surprises.
