The Latitude 64 Keystone is an understable putt-and-approach disc designed to prioritize high glide and a neutral, straight-flying finish. Approved by the PDGA in 2019, it serves as an excellent dual-purpose disc for both putting inside the circle and navigating technical, short-range throws down the fairway.
Physical Profile and Hand Feel
Beadless Rim: The Keystone does not have a "bead" (a small ridge of plastic on the bottom edge). This gives it a completely smooth, clean release off the fingers.
Rounded Edge: It features a convex, rounded lower rim that rests naturally and comfortably in the hand.
Medium Depth: It features a medium-deep rim profile (1.5cm depth). It is deep enough to catch the air for massive glide, but shallow enough to avoid feeling clumsy or "sticky" on release.
On-the-Course Performance
Depending on your skill level and how much power you give it, the Keystone adapts well to several specific scenarios:
The Hyzer-Flip: Thrown with a slight downward angle (hyzer), it will naturally flip up flat and carry perfectly straight down narrow, wooded tunnels.
Easy Turnovers: Thrown flat and hard, the understability kicks in, causing the disc to gently drift to the right (for RHBH throwers) without crashing or rolling over hard.
Perfect for Beginners: Because beginners generally throw with lower arm speeds, stable discs tend to fade out too early for them. The Keystone compensates for this by staying straight and staying in the air longer.
