Lighter, faster, stronger, the all-new Diablo Octane Golf Driver is fueled by Forged Composite, a unique new material from Callaway that allows superior distribution of clubhead mass, compared with all-titanium drivers. A lighter clubhead that retains an extremely high moment of inertia, the Diablo Octane Golf Driver powers drives beyond those of its all-titanium predecessor, the Diablo Edge Golf Driver, by an average distance of 8 extra yards.
DISTANCE: Lightweight head, super-large sweet spot and good energy transfer help some testers achieve bona-fide distance gains.
ACCURACY/FORGIVENESS: High-MOI clubhead assists in keeping bad shots from straying too far off-line.
FEEL: Stable sensation through impact despite lightweight design; several testers like the lively, "crushed it" impact feel.
