Just get rid of the 109s - in 190 you have a plane that is considerably better in all roles bar very high altitude fighter vs. fighter. They are (usually) not shot down like flies(unlike 109s) if they become out-E'd and outnumbered, too. Save a factory or two for G6/AS and later models, after just a few weeks you will have enough G-6 for a year to be used by your 4-5 high altitude squads, which you can fairly soon, before P-51 and longer ranged P-47s arrive in numbers, replace with G6/AS. If the Allies attack even Wilhelmshaven/Bremen area, they will have trouble keeping their bombers alive if you jump the formation with 400+ 190s a minute or two before the target. P-38s usually score 1:2 with the 190s through the altitudes, P-47s you can usually go around, or time it so that theres only one Group escorting. Works well early on, and by the time P-51 arrives, you will have G6/AS(at least) which can do 1:1 against P51s if not outnumbered(and if they dont run out of fuel/ammo mid-fight).
I havent ever gotten Doras yet, but it _should_ be an excellent fighter, if not bomber destroyer as well, at all altitudes. It just might be worth of it to research it before first quarter of 44 is behind, unless if you have House Rules against such. Very likely it can match P-51D/Mustang IV and later T-bolts, it has the disadvantage of 440 litre fuel tank only, but well, you're the defender and usually pick the fights you want. (yeah, then there are 300 P47s circling above your home plates... jikes!).
