**Pictures are of the actual discs. Colour/shade of the disc may vary slightly due to lighting.
Diamond is the choice of disc for beginners, children and players with moderate arm speed. It has an understable flight path with good glide and slight fade.
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.
