Latitude 64 says: River has taken the market by storm and is a disc with THE GLIDE. It´s easy to throw and fits most player's power and skill levels. River is a fairway control driver and while it´s not the fastest disc we have made, and doesn't have the widest wing ever made, it is a disc for accurate driving and good control. With small fade and amazing glide, you can really let it fly on to those big anhyzer curves.
Speed - Speed is the ability of the disc to cut through the air. Speed Ratings are listed from 1 to 13. Discs with high numbers are faster.
Glide - describes the discs ability to maintain loft during flight. Discs with more glide are best for new players, and for producing maximum distance. Glide is rated from 1 to 7.
Turn - is the tendency of a disc to turn over or bank to the right (for RHBH throws) during the initial part of the flight. A disc with a +1 rating is most resistant to turning over, while a -5 rating will turn the most.
Fade - is the discs tendency to hook left (for RHBH throws) at the end of the flight. Fade is rated from 0 to 5. A disc rated 0 will finish straightest, while a disc rated 5 will hook hard at the end of the flight.
