The best way to determine how a disc will fly is to have a point of reference. If you've thrown a disc with the 4 number flight rating system, you'll be able to relate your experience to their disc rating system, and determine how many other discs fly. If you're unfamiliar with terms like speed, glide, turn and fade, we suggest you check out how Innova's flight ratings system is designed. Many of the other manufacturers have adopted this system so you will understand just what their discs do as well.
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. Faster discs go farther into the wind with less effort. Slower discs take more power to throw, but have less of a chance to fly past the basket.
GLIDE| Glide describes the discs ability to maintain loft during flight. Discs with more glide are best for new players, and for producing maximum distance (especially downwind). Glide is rated from 1 to 7. Beginners looking for more distance should choose discs with more glide.
TURN| High Speed 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. Discs rated -2 to -5 make good roller discs.
