Cobra HS9 X-Series driver New for Summer 2006, the latest Cobra HS9 drivers are designed to precisely match your particular swing characteristics. There are three drivers in the line-up which in simple terms can be classified as low handicap/fast swing (X-Series) mid-handicap, average swing-speed (F-Series) and lower swing speed (M Series). This X-Series model has a neutral set-up and is aimed at stronger swingers with a current average drive of 265+ yards, swing speed of 104+ mph and ball speed of 150 mph. All HS9 models feature 460 cc titanium heads with the patented milled rhombus face geometry which creates greater flex across all points of the clubface, giving you more distance and accuracy for both on and off-centre hits. The Carbon Composite Integration in the clubhead's crown and sole allows weight to be shifted lower and further back, creating a higher moment of inertia and launch for longer, straighter drives. The precisely positioned Triple Weighting System, which lowers the centre of gravity and increases the MOI promotes the ideal ball flight and spin characteristics, resulting in longer and more accurate drives.
