Titleist stopped publishing bounce data on irons at least since the first T series if not the 716 or 718 AP irons. The logic was it wasn’t a reliable measure of turf interaction.
Adjusting the lofts of irons will impact turn interaction but most golfers won’t notice it much at +/- 1 degree. Lie adjustments can have more of an impact. Certainly the turf interaction from a T150 is significantly different than a T350. Why I prefer outdoor fittings for irons. The feel will be much more different than on an indoor mat.
