Ping eye 2 irons

Question
I have a full set of green dot eye 2's.  How do I tell what version mine are, the years that they were made, what their characteristics are?  Thank you.

Answer
Ted,

There is a code stamped in the hosel (where the shaft and club head meet). This has all of the information that you will need. Call Ping at 1-800-474-6434 and they'll be able to decipher the code for you.

Thank you,
