The amazing g20 irons ping is used by many golf professionals

The Ping G20 Iron Set is engineered for extreme forgiveness and predictable distance control. The cavity's floating CTP structure stabilizes the face and the aluminum badge with elastomer heel and toe sections produces a solid feel and sound. The CTP reinforces a 10% thinner face and controls distances while saving weight, which was added to the back flange of the deeply cut, multi-cavity head to increase the moment of inertia. Consistent, precise distance control was achieved by using a thin face backed by a floating CTP structure. Weight in the back flange of the deeply cut, multi-cavity head increases the MOI. Combined with PING's new CFS steel shaft, the G20 optimizes feel and trajectories. The hosel-to-head transition and clean appearance of the G20's inspire confidence at address that the ball will launch clean and easy from any lie on the course.
