I purchased two 915H with the S+ 70 shafts in them because I have always played a shaft about this profile. Well I got driver fit Saturday and the fitter recommended the whiteboard in my driver and fairway. He mentioned Id see a benefit in my hybrids as well. My question is to you guys is there enough difference in the shafts to tell honestly? I hit my hybrids for accuracy and not distance. I had bounced around putting a steel shaft in to try and curious what you guys thought of that.
