Coming on the heels of last fall’s introduction of the Titleist 913 driver is the release of metals and that are part of the same line – the 913 F and 913 F.d fairways and the 913 hybrids. According to Titleist technicians, the 913 fairways are designed to produce more distance from both turf and tee shots largely due to an improved Center of Gravity (CG) location. Part of that, they say, is a result of a thinner crown that allowed them to move the CG lower. And tests show that these new metals impart less spin and greater ball speed than those from the previous generation 910 line. At the same time, company engineers found a way to lower the shape of the sole profile of the 913 F as it also gave the SureFit Tour hosel structure a leaner look, all the while ensuring the club remained extremely adjustable, with 16 different settings and the ability for golfers to tweak lie and loft independently. As for the Titleist 913 F.d, it is designed to promote less spin and a more penetrating ball flight with a flatter trajectory. That version is available only in three lofts, 13.5, 15 and 18 degrees, while the 913 F comes in 13.5, 15, 17, 19 and 21. And the 913 F.d has a slightly larger club head than the 913 F, 188 cc in size versus 157 cc. More distance was also a factor in the development of the 913 hybrids, which come in five lofts – 17, 19, 21, 24 and 27. Here, the club maker employed progressive CG locations, with it being positioned toward the back of the lower lofted club heads, for greater forgiveness on off-center hits, and closer to the face on higher lofts to keep spin in check. Titleist also utilized a slight progressive offset through the lofts to promote confidence and proper ground contact. Visually, company engineers softened the toe shape of these hybrids and also gave the adjustable hosel in these sticks a more tapered look.
