I remember several years ago I was on the Mizuno shaft optimizer. It recommended heavy stiff steel. 🙄 I said that was a no go because of my elbows. They then recommended heavy stiff graphite. No go as well.
I ended up buying a set of Ping G15 irons with regular stock graphite. Played them for several years and shot my best score ever (par 71) at Fox Hollow.
Oh and they also recommended 1 and 1/2 inch over length and 4.5 degrees upright. Went with Pings color chart for height and arm length (green dot 2 up and standard length) instead and never looked back.
So basically I fit myself.
