What Latitude 64 say: A good short game is what ties everything together on the course. The Keystone is here to support you. It has a beadless, rounded edge and medium depth. The flight path is understable. With the Keystone you will get easy turnovers and straight flights even at low speeds. Build your short game on the Keystone and reach new heights!

Keystone (Opto)

  • Keystone looks and feels like a shallower beadless Ruru from RPM. The same sort of depth as an Innova Invader - placing it in the "Not too deep, and not too shallow" bin.

    With great glide, and a straight flight when thrown, Opto Keystone can be treated as a putting putter as well as a throwing putter - and in durable Opto plastic you know it won't beat in quickly of easily.

    Have a grabby/feely in-store, and we're sure you'll agree: Keystone is a serious contender.

    Flight Rating: 2 5 -1 1
