I am curious to hear what the guys have to say about this shaft! I have seen many tour pros ordering these for testing and a few putting it in play! Even the 115 X100! I personally have put them into my wedges and I love the softer feel. Many pros would go X100 in irons and then S400 in wedges. I went just a step further and did the S400 in mid and it has been great for that softer feel!
