The Prodigy D1 is an overstable, ultra high speed driver – we’ve given it a an astounding speed rating of 13 using the Innova system. Like all very high speed drivers, the D1 has a thick (2.3 cm) rim. Though the rim is considered thick, it is not quite at PDGA’s maximum width. The Innova Krait and Westside King share the same width as this disc. While the D1 is overstable, it isn’t a “meathook”, or one we would classify as “very overstable.” The D1 is a fantastic driver for power throwers, windy shots, forehand shots, and strategic doglegs.
