Ping's G5 driver is a proven stick but the new G10 has it beat. That's because the G10 boasts faster ball speeds (by 1 to 2 mph), higher moment of inertia (7 percent) and lower spin rates (200 to 400 rpm less) than the G5.
Ping says the output is five to 10 yards more carry, plus a shallower landing angle for more roll. The G10's updated head geometry includes a taller face that increases face flex (higher ball speed) with a more abrupt transition from the crown's highest point to the rear.
In addition, the clubface and crown are lighter and thinner than in G5. This redirects six to eight grams lower (reducing spin rate) and farther back (increasing launch angle and forgiveness).
A second driver, the G10 Draw, has more heel-side weight and a forward hosel (not offset) to help it close.
