Jade (Opto) USED9 6 2 1 The Jade is perfect for dedicated players who adored the Diamond, but require a disc with more speed as their skills progress. Its ergonomic design fits snugly in the hand and the texture of the plastic is pleasing to the touch. It holds its angles flawlessly, providing a reliable and moderately stable flight with just the right amount of turn and fade. A true gem for any player looking for increased performance.
