Cobra F Speed Fairway Wood. Cobra has taken their game-changing technology - larger face areas, dual weighting systems and rhombus face technology - and brought it to the fairway. Like the new Speed Series drivers, Cobra Speed fairway metals are built to match your swing and ball speed to optimize launch, distance and accuracy. There are three in the series - X Speed (extreme swing speed of 104 mph+), F Speed (fast, 87-105 mph - the model for the majority of golfers) and M Speed (moderate speed 76-97 mph). The Cobra Speed fairway metals complement the King Cobra Speed Drivers in providing increased distance, accuracy and forgiveness across the 9 'Hot' points on the clubface.
