UPDATE: Ping engineer called me today to clear it up. He informed me that it was a batch of irons that had been laser welded with an inaccurate weld material. They have corrected the issue and are replacing my full set. They sent me a label and are sending my sticks 2 day. If for whatever reason it has additional issues or does not meet my satisfaction they will work with me to find a new set within the current range and give me credit for the difference. All in all, fantastic experience with the exception of the issue itself.
That's the one right there. And nor should they send you a third... that's the right thing.
