Just went through this same quandary. Thought of ordering with specs irons online direct from PXG or Hogan. Best move ever was to go to club champion and get an iron fitting. They had so many shafts and heads it was truly awesome. I am 6’4 so it was great to have the right club length and for them to bend up each head to get me optimum specs on numerous shafts. My club head speed had dropped from my last Ping fitting approx 3 years ago, but the balance of that fitting was spot on except for shaft. I determined through the process that 1. I am mortal., 2. A regular shaft isn’t always regular and the same for stiff. 3. Fitting honed in the best dispersion, spin, carry and roll out for me. 4. I was left with the data and the opportunity to open my wallet and choose what I wanted, could afford and what I could live with. Goto a true pro shop for this, not Dicks or the galaxy. There are a lot of tricks to the fitting and interpretation of the data. Sent from my iPhone using Tapatalk
