And for smaller fighters (Lavochkins, Yaks, 109s, etc) I think 1/32 is my preferred working scale. Of course, a 1/48 Yak-3 isn't THAT far off from a 1/72 P-47...
Speaking of which...there need to be more VVS aircraft in 1/32. I know Trumpy makes the Mig-3, and there's an Il-2 out there. But the Yaks. The LaGG-3, La-5/5FN, La-7. They'll get there one day I guess.
