I’ve encountered very high and short shots (well short of the green) with the short irons. Is it common to hit PW/9-iron with 6 degree flat lie angles higher than normal? Or perhaps does it suggest a swing flaw?
Bend it a bit upright and see if that improves trajectory and distance. I would be surprised if it’s only the lie angle causing that, but a quick experiment can provide evidence.
Bad grooves, lofts messed up, heavier heads, weaker shafts, etc… could all contribute to too high a flight. And, of course, swing characteristics could cause that.
