The Latitude 64 Keystone is a putter with unusual glide — five is high for a 2 speed, and it changes what the disc is for.
That glide plus a point of turn makes it a driving putter rather than a pure putt-and-approach disc. Thrown flat it holds a long straight line and keeps floating instead of dropping, which gets you distance you would not expect from a putter. On the green that same glide can carry it past the basket, which is why plenty of players throw it and putt something else. One fade is enough to bring it back gently without pulling it off line.
How much the Keystone turns and fades depends on how hard it is thrown. These three shapes are drawn from the manufacturer’s numbers, not from measured throws.
