I just received my AP2 712 iron with steelfiber i95 R shafts and cannot be happier. I wanted to get the steelfiber i 80R but was told these were not approved by Titleist for the AP2 irons. I am a senior golfer and find it very hard to find a traditional iron, no offset or large head, or a lighter shaft. While I can still handle the i95 shaft my club speed with the i 80 shaft was about 3 to 5 mph faster at my age every yard counts.
The steelfiber shaft is the best shaft I have used in the last 10 years. I hope Titleist will look into making better clubs for seniors. My fitter wanted me to get the AP2 irons with a steel shaft and then swap them out for the i 80's at $100.00 per club,that's a little to steep for me. Titleist has hit a homerun,for me, with their Drivers ,fairway metals and hybrids with the Bassara shafts, I hope the can do it for their irons as well.
