Cobra F Speed LD 2008 driver. New and improved for the 2008 season it is designed for the fast-ball-speed player, which most golfers are, the all-new Speed LD F driver delivers an impressive 5000+ MOI for greater distance, accuracy and consistency. And the square alignment and precisely tuned clubhead and shaft generate high launch with a slight draw bias, providing a much higher level of performance. The F Speed LD range is aimed at those of you with swing speeds in the range of 87-108 mph
