The D2 is a fast and overstable driver deisnged for strong throwers. It will be slightly less overstable than the Prodigy D1. The D2 is meant to move straight and overstable in any condition, with minimal side-to-side movement for extra accuracry when you need it. It will be a driver that excels at backhand and forehand shots. The 400 series is a premium blend of material that is extremely durable. The unique blend of plastics feels as good as it looks and will be able to be broken in over time. This tour quality plastic gives the thrower better grip even when it is wet.
