There are two models of the Titleist 905 drivers, the 905T and the 905S, and they can be purchased with degrees of loft ranging from 7.5 degrees to 11.5 degrees. In these models, the center of gravity is lowered, which helps provide additional distance. These drivers produce a higher ball trajectory, which generates more spin along with added yardage. A number of shafts can be paired with these clubs. It is left up to the individual which shaft option best suits them.
