Ive had all of them except the 8, 9 and pw reshafted because I broke them. The three clubs I mentioned are the only ones I havent broken. I bought the irons from my brother and the shafts were about 3 years old. After breaking them off I had them reshafted, except 8, 9, and pw. After having them reshafted I eventually broke those off, with the 3 I broke yesterday, they are all broke except the 8, 9, and pw. I dont really believe what the local pro told me because of what u said, mickelson used graphite and he has some serious club speed. But its not just the 845's, I have broken 2 taylor made irons with graphite (3, 6 iron). I have never broken a driver or 3 wood but I have snapped 2 adams tight lies fairway woods. Im a fairly good ball striker and when this has happened I hit the ball flush and the ball traveled good, its not like I shanked it off the hosel. I love the feel of graphite shafts and would like to put graphite on my main set of irons, titleist ap2. But every time i snapped one off, I was really trying to rip the ball and when I try to really muscle the ball my downswing can be, the best word to describe itb would be violent, lol, smooth but very fast hips and alot of push with my legs. This just makes me hesitate on putting graphite on my ap2
