Thanks for all your inputs. Really need something super forgiving here as I don't have much practicing time. When my swing is off (which is quite often), I need something which can still let me aim and land on the green (may be too much to ask for?).
For example, shots played with my set of Epon 503 (which was club fitted) may tail off left or right just outside the green (into bunkers, roughs or other hazards), whereas the set of ONOFF Red irons (2012 version) I recently tried really let me shoot for the green. So...ooo forgiving.
Will try to demo the VG3 Type E.
