The brewster was statistically insignificant
Im aware if its operational #s.
We dont do SEA setups with absolutely historic side ratios and/or OOBs and the players would not want them.
Next time you see a Ta-152 or an Me-163 in a setup remember your comments above. The B-239 is hardly the only
rarer type we have ever used in FSO. Look at the real operational #s of Ki-61s deployed in the SW PAC, you want us to go down that road? really?
Maybe a few players would like to try out the Finnish Brewster? so what. 24 max is hardly some huge outlandish # for FSO. The strength of SEA setups is that no two designs are ever the same. You can design them with some a/c left out, and some included. Next time I do a 1943 Fin-Rus setup maybe I wont have the B-239. Maybe I will have a VVS B-25 and no Boston III. Who knows. There is no one way "cookie cutter" way to do them and I think thats a good thing.
Re the plane set. You can have setups that are based on WW2 or you can have 100 percent "fair" setups with both sides in P-51s with a 50/50 split on a flat terrain. Are some setups advantageous to one side? yes, but over many setups hopefully it evens out a bit. With this one? I guess we will see. Its not a plane set we have not used before in Snaps, Scens and prior FSOs..."Dogs of War" is my FSO design and I dont recall a big prob for the Allies or the Axis with a similar plane set.
