Callaway Golf Big Bertha Fusion Irons Graphite Shaft 3-PW R/H

Description: Scottsdale Golf Website Says: "Tunite alloy cradle (the main body of the iron) was created by Callaway and allows for 77% of the clubhead mass to be positioned around the perimeter of the iron, creating extreme perimeter weighting through an ultra-high Moment of Inertia (or MOI) which is the measure of a club?s resistance to twisting. More resistance to twisting in your clubs gives you exceptional stability and straighter shots. Lightweight, formed 6-4 titanium face insert creates a clubface that is 35% lighter than a comparable steel face. That frees even more mass to be distributed around the perimeter. This grade of titanium is one of the strongest titanium alloys; the "6" refers to the percentage of aluminum (6%)and the "4" refers to the percentage of vanadium (4%) in the alloy. The 6-4 titanium is heat treatable with excellent strength and is widely used in the aircraft industry and in turbine applications. Thermoplastic Urethane (TPU) SenSert layer (the back of the club) is a chemically engineered polymer that is tuned to interact with the titanium face to give Big Bertha Fusion Irons a crisp and responsive sound while reducing vibration at impact for incredibly soft and pleasing feel. Refined new head shape gives golfers a more traditional look while maintaining all of the forgiveness of an oversized game-improvement iron. The new head size provides confidence at address for both the average as well as the more accomplished player.
