• Uniquely tuned to produce a sound (or feel) to match the power inside every iron • Center of gravity location in each head is precision-placed to optimize long, middle and short-iron flight• Inverted Cone Technology promotes faster ball speed on mis-hits for consistent distance • Each iron is individually engineered to promote distance and uniform distance gaps• Multi-functional sole lowers the center of gravity and reduces turf-drag to make it easy to launch shots high and long• Every individual iron boasts a different face thickness - the thinnest and fastest occur in the long irons, with the face in each successive iron growing thicker down through the middle- and short irons • The thinner face promotes more ball speed and distance while the thicker face provides greater feel
