I now play the X12 irons and couldn't be happier. The Memphis 10 shaft fits me perfectly and they feel as good as any iron that I have ever tried. I was going from iron to iron trying to find a set that I could be happy with. I remember having a set of X12 knockoffs years ago and played some pretty good golf with them, So out of desperation I bought a set of x12's about three months ago that were in very good condition off of ebay. I haven't shot above a 78 since I bought them. They are in the bag to stay.
