i typically have a wingman and when we see hiiiiiiiiigh 67s we work him like cattle. the only way we have found to kill ALL 3 of his buffs.
i fly buffs more lately than i use too, my tgt alt depends on what why when and where. bostons 300agl-8,000' 2 hangars or occasional town if hagars are dead. B26s 5,000-12,000' hangars/town or a string of dar, also my strat raid bomber. Ki67s 8,000-18,000' towns ords or town. Mossies are 20K+ everytime unless its a quiet arena or im leading a "droop snoot" mission. If they every add the B25J then ill be in it all the time hitting any target i please lol
Im rarely in 4 enginged bombers, so they dont count.
