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. Players will be able to count on a hard finish, 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.
AIR Spectrum is a line of premium, lightweight discs. They are engineered for the same shot performance of their heavier counterparts with added glide.
