Schweigert said that a tungsten toe weighting system in the 17-4 stainless steel heads of the Ping i20 irons enhances forgiveness throughout the set and makes it easier for players to shape and control shots, while stabilizing bars work with a slightly thicker clubface to bolster distance control and feel.
The long irons are slightly larger and launch higher, he said, thanks to a vertical Custom Tuning Port that allowed Ping to position the center of gravity a bit further back in this model as opposed to its predecessor, the i15. The big difference comes in the revised custom tuning port in the back of the head, which now slots in behind the face and works with the stabilising bars to increase the forgiveness from the same sized head.
The new clubs are listed as having the same swing weight but in my opinion the i20s feel much lighter. They do not produce the feel of a forged Mizuno iron but it is not much short of this and although fairly forgiving, you know when contact is poor.
Each of the i20 irons comes with what Schweigert calls “foggy chrome” finish and ferrule for a cleaner, more high-performance look. While they will sit in the Ping line between the cheap K15 irons and G20 models, they’re designed to appeal to golfers of all abilities.
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 cheap Ping G20 irons′ inspire confidence at address that the ball will launch clean and easy from any lie on the course.
Ping's stock grip provided plenty of grip when tested in both dry and wet conditions. It is slightly thicker than most stock offerings and was an impressive performer. Extreme perimeter weighting within the stainless steel head helps to improve forgiveness and accuracy. This extra weight is found by making the face of the club extremely thin.
The cavity badge is made from aluminium with soft elastomer in the heel and toe. This helps to provide a better feel. The hosel-to-head transition is designed to inspire confidence. The cosmetic changes do not reflect the improvements made. The new CFS is the steel stock offering from Ping. It helped to produce a long flight on test. The TFC 169i is the graphite offering and will help anyone looking for a higher launch.
All round I think Ping have produced a great iron with the i20 model and it should appeal to all golfers up to around 15 handicap. As a senior golfer who's handicap has just gone up to double digits, I am pinning my hopes on these cheap golf clubs getting me back down.
