I'm not reading the whole thread, but will comment that bombers are easy kills most of the time. I haven't played much of late (summer fun'n), but over the winter one month I was 14v1 against B-17's, arguably the toughest bomber out there.
If you are having trouble with bombers, feel free to look me up and we can go bomber hunting. I am not a Lusche, but bomber hunting is one of my "things"...
