Ping i3 driver. Applying the proven technology of the TiSI driver, including a nearly parallel top and sole and variable face thickness, Ping engineers designed the Ping i3 Series metal woods for golfers who preferred a smaller clubhead size. At 198 cc, the driver offers workability off the tee, yet is extremely forgiving. Driver lofts available in 7°, 9°, 11° and 13°
