Lightweight Titanium Face The irons feature a larger, lightweight face that saved 27 grams, which were allocated to the perimeter and the sole to increase MOI. Wider Sole An extra-wide sole features a low and deep center of gravity to promote high trajectories and low spin. The sole geometry also keeps the club from digging for added control. Toe Weighting A large internal weight pad significantly increases the MOI and stabilizes the club face for consistent distances across the hitting surface.
