River is one of our most popular discs of the past decade, probably due to its tremendous GLIDE. The River is a fairway driver for those accuracy shots that demands good control. It is easy to throw and fits most player's power and skill levels. With small fade and amazing glide, you can really let it fly on those big anhyzer curves.
 
Flight Ratings: Speed 7, Glide 7, Turn -1, Fade 1.
 
About the plastic: Opto Air uses the same durable material as the Opto line but is modified to be lightweight which is perfect for beginners.
