The TaylorMade Rocketballz Iron Set is engineered to hit longer and straighter with more accuracy and better feel. The two-piece metalwood-inspired construction in these irons create a low center of gravity and a high coefficient of restitution. The coefficient of restitution is the measurement of energy lost or retained when two objects collide. A higher "C.O.R." means more energy is retained, and a cheap golf club with a high C.O.R. means consistently longer shots on the golf course.
