FYI: 1945 aircraft in this game, off the top of my head include:
Ta152H-1
F4U-4
P-47N (?)
109K-4 (Dec of '44, but how quick did they get to the units?)
La-7 (our 3-gun option was only around in the closing months)
EDIT: QuitV, the SEA has almost 300+ players in it many times during Fridays, Saturdays, Sundays, and even spreading into other days of the week. There are enough things taking place in there that it often has as much as either LW arena, depending on the time. Don't discount how many frequent the SEA.
