Cleveland CG Gold Irons. New for 2007, the Cleveland CG Gold irons are an all-ability iron designed for the player who wants to maximize forgiveness while still maintaining a solid feel in a traditional head design. High and low handicappers alike are drawn to this club's performance. Cleveland Golf's newly patented Gelback Technology consists of a lightweight, visco-elastic, vibration-dampening material, which is placed directly behind the hitting area of the clubface in the back cavity of the iron. Gelback is vibration-tuned to remove unwanted vibration on mis-hits while still allowing the player the necessary feedback from the clubhead's soft yet responsive feel. The superior I-beam structural design of this next generation of MCT helps provide the highest strength possible to the topline of these new CG GOLD irons. The stiffer topline allows the face to remain undistorted and square through impact for more consistent and accurate shots. Impact vibration waves are also shortened by MCT, thus giving these irons a much more solid feel compared to traditional iron designs. This latest version of MCT not only provides added stability and forgiveness but also allows these irons to boast a 15% increase in their centre of gravity (CG). This improved CG has been achieved by redistributing 10 grams of weight to lower and deeper locations on the clubhead. Designed with Royal Precision flighted technology, the new CG GOLD steel shafts provide an exaggerated change in kickpoint within the club set which helps control ball flight. The long iron shafts are designed to launch higher and provide more spin to keep the ball in the air longer. As the set transitions into the short irons, the ball flight becomes slightly more penetrating to provide increased accuracy and maximum spin for control.
