Discraft's Elite-X line is made of a more durable plastic that is easier to grip. The glass smooth surface helps keep releases clean and consistant and decreases wind resistance. This plastic molds incredibly consistant so that you can count on the same flight characteristics disc after disc. These discs quickly found their way into the bags of Pros everywhere.
Elite-X Cyclone 2 - (165-176)[21.3cm] - A more overstable version of the Cyclone with a slightly higher rim. A great disc for big arms. Holds its line well into the wind.
