The Jade is designed to be a little more stable for players who loved the Diamond, but as their game developed needed a disc that could handle a bit more speed. It sits very comfortably in the hand, with a good tactile feel to the plastic and it holds the angles well. You CAN turn it over but unless you really force it, it fades back at the end. A very nice, reliable, and moderately stable disc.
Looking for lightweight discs? For the Opto Air we use the same material as our durable Opto Line plastic. It is however slightly modified with a different process to achieve a stunning result of lighter weight discs.
