In addition to the above, G20 Irons combine with Ping's new CFS steel shaft to optimize feel and trajectories. An incredible thing to me, I won this set of irons in a tournament. The irons gave me the confidence waht I need in the golf games. I can hit more greens and gett more reasonable birdie putts than ever before. With the help of Ping G20, I can hit average 170 yards. Trust me, it is my experience share for you, you will recogize the difference with the old irons you have used when you use the incredible irons.
