All the D Series distance drivers are designed so that the flights are extremely consistent with a narrower flight path than conventional long distance disc golf discs, making them more accurate and much more forgiving. 

The Prodigy X Series is built for speed. These discs are low profile, high speed distance drivers. With less rim depth than the D Series, X Series discs are faster out of the hand and will offer similar glide to the D Series. The X Series discs are perfect for long wooded shots or accurate turnovers.
