Diamond is the choice of disc for beginners, children and players with moderate arm speed. It is only produced in weights between 145g-159g, which makes it easy to throw and control. It has an understable flight path with good glide and slight fade.

Opto Air Line Plastic 
Opto Air uses 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, but keeping the same weight distribution as close as possible to the Opto and Gold Line discs. 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.
