Been a Callaway follower for several years; thought I would get the latest; greatest an see how they would perform. I read all the reviews; but as reviews go..it is all up to the individual golfer. I'm very glad that other's have seen a great increase in their golf game; but for me...that just did not happen. I had them on the course all day long; and it was like I was hitting a rock; I felt it all the way through my hands/wrists. Using my same swing; they just felt out of sink for me. They were under the 30 day playability, so these clubs went back so some one else might benefit far better than I did. Callawy makes great products; I have other sets that I swing the same way; no problems with them. Just never met my expectations.
