Callaway sin egen beskrivelse:

Callaway Diablo Octane Drivers Introducing Forged Composite, a revolutionary new material that is lighter, stronger than titanium. The Diablo Octane crown is made up of more than 10 million individual turbostratic carbon fibers, creating a lighter clubhead that retains an extremely high MOI. The lighter weight also allows for a longer shaft that generates faster clubhead and ball speeds that add up to an average of 8 extra yards off the tee compared to the Diablo Edge Driver. That's performance an all-titanium driver just can't match. * Forged Composite™: Revolutionary new material that's lighter, stronger than titanium, with 10 million turbostratic carbon fibers that reinforce 33% of the clubhead. The lighter clubhead still has an extremely high MOI and allows for a longer shaft that generates faster head and ball speeds for an average 8 extra yards over Diablo Edge™ Driver. * Hyperbolic Face Technology™: Produces consistently high ball speeds across the face by using a chemical reduction process to selectively remove excess material for precision thickness control. * Project X™ Graphite Shaft: Longer, high performance shaft is designed as the ideal complement to the Diablo Octane Driver to maximize performance and enhance feel.
