Ping G400 Max Driver
Instead of employing moving weights, Ping makes variations of the same driver for different swing styles. On the extreme end of this year's crop is the G400 Max. Designed to add distance to your drives, it has the highest moment of inertia of any Ping driver, thanks to a deeper profile, higher-density weighting, and ultra-thin, flexible face. All of that combines with acoustically tuned interior ridges and an aerodynamic shape to produce shots that are long, straight, and sound as good as they play.
