Sub 70 699 v2 Irons - A Three-Year Journey to Golfing Excellence The Sub 70 699 v2 Iron in black finish, designed as a game improvement distance iron, represents a triumphant culmination of three years of relentless research and development. This journey has led to the realization of an elusive goal—achieving improved distance, forgiveness, and playability in perfect harmony. VFT Face Technology: The redesigned 699 retains the successful 2-piece, TPE resin-injected, hollow body design in 431 stainless steel. The game-changing addition is the reactive 1.7 millimeter thin VFT (Variable Face Thickness) face, composed of S-450 aerospace steel. This not only delivers improved distance but ensures more consistent distances across the entire face. Even imperfect strikes on the toe or heel result in minimized distance loss, translating to more greens hit. Enhanced Forgiveness: The new model is a true game changer in terms of forgiveness. The expanded channel back design elevates forgiveness on off-center strikes. Two reinforcing ribs within the head reduce body deformation at impact, maximizing energy transfer and boosting ball speeds even on off-center hits. Improved Playability: The 699 v2 iron showcases enhancements in playability, including a squared leading edge grind for easier alignment at address and a sleeker top line. The sole now features a 4-way camber, enabling a perfect setup at address and delivering superior situational playability. The sole allows for workability in any direction, high or low, right or left. Shorter, constant-length hosels lead to improved CG (Center of Gravity) positioning, and new offset progressions promote better Dynamic Alignment Properties for predictable directional performance.
