The D2 Pro is a very overstable, high-speed distance driver. The slimmer profile gives it a similar feel in the hand to the D2 Max, but the D2 Pro significantly cranks up the overstability. Many players will be able to count on a hard fade, and those with higher arm speeds and more power can get a similar flight to the D2, but with slightly less glide and a stronger fade.
500 Plastic was development over a considerable period of time to formulate a blend based upon player feedback. It has a stiffer, less gummy feel than 400 Plastic. The 500 blend provides an extremely confident grip on the firm, yet flexible flight plate. It also provides a very solid feeling rim.
