PKR-CUP A new Cup Face design combined with Wilson's AI generated Variable Face Technology optimizes ball speed, distance and consistent launch windows. VOC "VELOCITY OPTIMIZATION CHANNEL" A channel located in the sole and behind the face allows the face to flex for maximum ball speeds. LOW CENTER OF GRAVITY & HIGH MOI Toe-biased weight distribution makes Dynapower Forged irons faster, more forgiving and higher launching. ENHANCED SOUND AND FEEL Topology optimization allowed us to place mass and material throughout the head for enhanced stability on all hits as well as improved sound and feel. OPEN HEEL CONSTRUCTION Mass pushed toward the sole and toe increases launch and forgiveness. LOW CG, HIGH LAUNCH Placing the CG low in the sole provides high MOI and a higher launch to create to create maximum stopping power.
