I am very please with this iron shaft, I have put it in my 5 and 6 irons. I generally have a low launch to my irons, and my 5and 6 would always roll through the greens, when I lucky enough to hit them. These new shafts really get the ball up in the high, closer to what my usual seven iron does. This helps increase distance and helps it check up on the greens. My 5 iron went from 180-185 to 190-195 on a good swing.
Pros: Quality, Durability, Easy to Use, Good Value
