F1The F1 is the most overstable of the Prodigy fairway drivers. This disc is currently available in the quality series 400 plastic, and utilizes Prodigys easy release technology. Prodigy describes the F1 as a medium speed, significantly overstable fairway driver with predictable controllable flights. This new disc will excel in all wind conditions and will work well for overhand tomahawk and thumber throws.
