NEW 2018 Callaway Epic Pro Iron Set 4-AW Project X LZ 6.0 Stiff Flex Steel

Callaway GBB Epic Pro 8PC Iron Set - Steel Innovation without boundaries To develop Epic Pro irons, Callaway pushed themselves in a way that they could elevate performance to the highest level they ve ever achieved in a compact players shape. It had to provide the absolute best combination of ball speed, distance, forgiveness, accuracy, control and feel. And to go beyond that standard, they had to be extremely meticulous, creative and committed to carefully crafting each material. Callaway has been the #1 Iron in golf since the beginning of 2015. While developing Epic, they started by improving the technologies that made them the category leader. And Callaway s revolutionary 360 Face Cup is the technology that truly led them to #1. The Face Cup incorporates an ultra-thin rim around the perimeter of the inner side of the face. At impact, the rim flexes and rebounds to add ball speed on center-face hits and minimize ball-speed loss on off-center hits. It s especially effective on the most common mis-hits -- toward the toe and low on the face. To further improve face performance, they increased the rim s flexibility by reducing the thickness to 1 mm at its thinnest point, resulting in even faster ball speed on center and off-center hits for more distance. Every iron in this set is uniquely constructed to promote optimum performance. During development Callway studied and tested new ways to enhance launch and trajectory, and succeeded by introducing an incredibly high amount of MIM ed tungsten (over 664 grams in the set) into their Internal Standing Wave technology. MIM ed stands for Metal-Injected Molding, an injecting-molding process using finely powdered metal to create intricately shaped parts with tremendous precision. Tungsten is relatively heavy, which allowed Callaway to control the head s internal weighting so that they could give each individual iron its own optimized CG location. To do this, they engineered a precise amount of tungsten
