No, all the King Cobra Speed Drivers are confirm with USGA regulations (United States golf association) and they have the largest clubface in golf, which, combined with Cobra's advanced face technology, optimizes flex across the entire face which provides increased ball speed and distance. Then from head to shaft to grip, every King Cobra Speed model is tuned to specific player profiles which increase their ball speed, distance and accuracy. King Cobra Speed Drivers are available in four models: the XX/Speed, X/Speed, F/Speed and M/Speed.
