Quality is excellent. Very solid feel at impact, and top quality shafts are used.
Did the whole fitting thing with measurements and answering some questions. Started out with the standard lie model. After hitting some balls, did the lie angle test with a lie board, and was hitting a bit toward the toe, so went to the Yellow version which is 1-1/2 degrees upright. Dead center on the lie board with this iron. Club felt very solid and nice narrow sole and top line.
Nothing not to like.
Excellent set of irons, for me at least. I hit the 7 iron in the fitting and it felt great. Not sure I believe the distance numbers from the simulator. Hit four balls down the middle, first two dead center and within a few feet of each other. shortest shot was 190 yards, and long of 210 yards. I didn't believe the numbers, and neither did the Ping rep. One more reason I don't believe the numbers from a golf Simulator in the stores.
