Callaway Big Bertha Fusion Wide Sole Irons

Callaway Fusion Wide Sole Irons. New for 2007. Callaway's premium top-of-the-range irons use innovative Fusion and weight distribution technology and advanced multi-material design to create an oversized game-improvement iron. 3 distinct materials are brought together to create the Fusion Wide Sole Irons: Lightweight 6-4 Titanium Body which is 35% lighter than a comparable steel body, allowing Callaway to create an oversize clubhead with increased offset for greater forgiveness, an increased effective hitting area and more confidence. A dense alloy, Tunite Sole Weighting in the sole of the clubhead dramatically lowers the centre of gravity to help get the ball in the air quickly and easily. A special vibration-dampening Thermoplastic Urethane (TPU) SenSert Insert composed of a chemically engineered thermoplastic urethane that decreases vibration and creates an incredibly solid feel. The wide sole design instils confidence and helps each iron in the set glide smoothly and easily through the turf to reduce clubhead digging on missed shots.
