I have a Callaway 18 degree utility prototype iron. It has a dynamic gold S300 steel shaft on it and I have trouble getting it up into the air. I used to kind of cast the club adding loft so this wasn't a problem until recently. Now Im staying more on top of the ball and I think this is causing me to hit the ball with a little shaft lean. I was wondering if anyone think replacing the shaft would help me get the ball into the air faster and which shaft would work best. Any help would be great.
