I have put my new 714 AP2's to use and after several rounds, the black numbers that ID the irons on the sole, have begun to wear off (some almost completely- scoring irons). My club has a grass range and I don't hit off mats. I am wondering if this is a common issue for folks for the 714 AP2's and/or some sort of design flaw? My previous set of 735 CM's, which I had for almost a decade, never had this issue.
Thanks in advance!
