The Callaway Diablo Octane Driver is fueled by Forged Composite, which is the lightest, strongest material ever used in golf clubs, giving it a significant performance advantage over all-titanium drivers. Created in conjunction with Lamborghini, the Diablo Octane is eight yards longer off the tee than last season's Diablo Edge. Lighter overall than previous drivers, the Diablo Octane is fitted with a 46-inch shaft instead of the standard-length of 45 1/2." The longer shaft should help golfers create more clubhead speed and power for distance, distance, distance!
