Progressive lengths and lofts and a thin face optimize launch conditions and generate faster ball speeds, ensuring maximum distance and control to consistently knock the ball close. The Custom Tuning Port (CTP) contributes to a solid feel and a low-back CG for launching the ball high and straight. Slightly longer heads also boost MOI for improved off-center performance, and a new sole design promotes solid contact.Distance, forgiveness and high launch enable you to launch the ball farther and higher so you can attack the pin. Progressive lengths and lofts and a thin face are key to achieving a higher max ball flight to give you the stopping power needed for scoring. Distance control and consistent, predictable results are provided by a custom tuning port that sits very low and supports a thin face to generate faster ball speeds. The CTP and an undercut cavity help position the CG low-back to optimize launch and forgiveness while ensuring a solid feel to inspire confidence.With distance also come forgiveness and accuracy. Slightly longer blade lengths help to increase MOI, most noticeably in the 4 through 7 iron. Progressive offset generates higher ball flights in the longer irons and penetrating, controlled trajectories with the scoring clubs.Another advantage is a sole design optimized to promote solid contact with consistent trajectories. To improve turf interaction, relief was added to the lead and trailing edges, and bounce was refined to perform with any angle of attack. A soft elastomer badge further contributes to improved feel and sound in the perimeter-weighted design.
