This classic pear-shaped hybrid offers stunning good looks, an aerodynamic design and advanced weighting to deliver a higher moment of inertia (MOI, the club’s ability to resist twisting and impart greater force). The Bazooka features two internal weight cavities in the heel and toe that lower the center of gravity and move it deeper in the club head for a high launch and great forgiveness.The set’s progressive design can be seen in each iron’s different blade length, face height, top line, offset, bounce and MOI. This optimizes the club’s performance in distance, trajectory, spin, bounce, forgiveness and accuracy. The long irons (3-5) feature a wider, hybrid-like blade length, thicker sole, and progressive undercut cavity for greater forgiveness and higher-flying shots. The irons’ larger top line, offset club head and minimal bounce inspire confidence even from the most difficult lie. The mid irons (6-7) feature a shorter blade length, less offset, more bounce and a smaller top line and sole for greater workability and shot making. Finally, the scoring irons (8-PW) feature a smaller undercut cavity, the least offset, the most bounce and a slightly larger sole than the mid irons for shots that get up quickly and stick close to the pin.
