I fly with the X now and am very familiar with it, however not with the helmet. I have quite a few BFM sorties with the Mig-29/AA-11 PTM so understand how to push the High Off Bore Sight (HOBS) fight. The helmet / 9x / AA-11 isn't the end all be all. The fundamentals need to be understood and applied correctly to achieve the desired outcome (Mig / Flanker driver in the chute). The guys I fought had a breakdown in the latter regardless of the weapons / toys they employed. However, when asked the right questions in the debrief it appeared the light was on!
