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.
Opto line is made out of some of the world’s most durable plastics. It comes in a variety of beautiful translucent colors. The Opto line plastic has been developed to withstand severe punishment and extreme conditions better than other plastics.
