Finally bought my dream irons, a new set of regular T300’s. Used for three months and noticed that the face of my 7 iron is now significantly concave. I’m 54, 5’7 and 160 lbs; not a muscle player. These were to be the last set of irons for me. Has the goal of thin face irons with max spring gone too far? Pretty sure the warranty will cover it but now I’m not sure about the longevity of these irons should I replace them. I had a set of DCIs for about 30 years with no issues. Life long Titleist enthusiast, what should I do?
