The head of the Callaway Diablo Edge driver is made from ultra-thin four-piece titanium with aerodynamics helping generate higher ball speeds and its 'chemically-milled face making it more forgiving.'The Diablo Edge standard driver is available in 9-, 10-, 11- and 13-degree lofts as well as a draw version.And 8.5-, 9.5- and 10.5 in a Tour model.
