Something very similar is running in FSO right now. One question I asked, and I'll ask it here:
Fw190A-8 is hopelessly outclassed by all those allied fighters, ESPECIALLY at alt, so how about ditching it, moving the 190D to its slot, and putting in the Ta152 in the 190D's slot?
It's not like the 152 is a major threat to fighters, but it would actually be able to perform above 15k (unlike the 190a8)
Just a suggestion!
