The 2018 Project (a) golf balls feature a three-layer design. The Dual-Distance core features a larger, softer inner core that reduces spin and feels great while the stiffer outer core increases velocity and rebound. You get less spin off the driver and long irons with more greenside spin in connection with the soft urethane cover. They've also included the same 322 dimple pattern used on the TP5 and TP5x golf balls for less drag. Less drag means more speed and more speed equals more distance.
