This disc has minor yellowing around the rim!
This is a 177g white Latitude 64 Keystone in Retro plastic, from the 2019 Trilogy Challenge Prototype run. Prototype Trilogy Challenge discs were made available in limited quantities at Trilogy Challenge events, making this one a genuine collector's piece from that season.
Retro is Latitude 64's baseline-style plastic, offering a soft, tacky feel straight out of the bag. It provides excellent grip in most conditions, though it will beat in faster than premium blends. For a putter that lives in your hand, that texture is part of the appeal.
The Keystone is a straight-flying putt and approach disc built for reliability inside the circle and off the tee. Expect a very slight high-speed turn with a gentle, consistent fade at the end, which makes it easy to throw flat and straight. It handles short and mid-range approach lines well, and its neutral flight makes it a dependable go-to for straight hyzer putts from longer distances.
The 2019 Trilogy Challenge Prototype stamp marks this as part of the limited run tied to that year's event series, shared across Dynamic Discs, Latitude 64, and Westside Discs. These prototype runs were not available through normal retail channels, which adds to their appeal for collectors and Trilogy fans alike.
Disc golfers who want a reliable, straight putter with a soft, grippy feel, or collectors looking to add a legitimate Trilogy Challenge Prototype run to their shelf. This one has only storage wear and no ink, so it is still in excellent shape.
