Utilising VTF Technology the varying level of face thickness in the Diablo Fairway Woods result in higher ball speeds from a larger area of the face for that all important distance. The Diablo delivers this unparalleled length without sacrificing accuracy thanks to Callaways discretionary weighting that moves weight from the hosel to the perimeter of the club to maximise impact stabilty.
