Here's what Innova has to say about the Roadrunner:
The Roadrunner is a long-range distance driver with lots of glide. It makes an excellent finesse driver or long range roller. Power throwers can use this disc for long turnover shots and rollers. Less powerful throwers can use this disc for long, straight shots or low tunnel shots. One of the best Distance Drivers for turnover shots.
Speed: 9 Glide: 5 Turn: -4 Fade: 1
