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 Air uses the same material as our durable Opto Line plastic. It is modified and the runs are done in a different way to achieve a stunning result of lighter weight discs that still has a layer of solid plastic at the tip and bottom of the rim to protect the alternated material that is mostly centered in the middle of the rim but also spread out slightly over the top of the discs to keep the weight distribution as close as possible to the Opto and Gold Line discs.
