Being biased toward Allied aircraft doesn't automatically award the mantle of 'expert'.
I have review virtually ALL the 355th FG encounter REports and Marcs. More were lost to 109s (FAR and away) than Fw190 or Fw190D's. I would say most 355 aces found the Fw190 to be easier prey above 15,000 feet - all relative because of pilot quality.
You dont need to tell me this. Tell that to the people that I am talking about.
