Ping TiSI Tec. The Ping TiSI Tec driver improved on the custom-fit TiSI titanium driver by making it even longer. Using new Chemical Milling Technology (CMT), the walls of the driver were made thinner and stronger in a process that removes the 'alpha' layer that forms during the casting process. The weight that was removed was redistributed in the form of weight pads that were cast into the soleplate of Ping TiSI Tec. By positioning these pads close to the face in the heel and toe of the driver, Ping engineers were able to optimise the spin rate of the golf ball for a significant increase in distance.
