KCee Some of the heavier shafts are too stout for me.
Try FST Pro 115 A/R .370p Value had some. 115g at 43" after tipping wind up in the 100g 5i 38" range Won't break the bank or Nippon 950GH .355t or .370p.
BTW one needs to factor in mid-iron club head speed, transition time and release early-mid-late. Most don't know these stats. when they are self fitting.
KCee I can almost always start hitting the lighter stuff on the indoor launch monitor, but it doesn't always carry over to the course.
It never does. 😉
