Dual Rail Sole Design. Center recess section to reduce turf drag and improve turf interation. Allows better playability from the rough and poor lies. * Mitsubishi Diamana Red 74 Shaft. Higher launch angle optimizes trajectory and angle of descent. More carry distance and steeper landing angle for hop-n-stop control. * Parabolic Leading Edge. Progressive transition of leading edge bevel improves turf interaction at impact. Adds forgiveness by allowing club head to slide across the turf instead of digging into the ground.
