i grabbed them all and played around, Prefered Fruda's start stop sounds for the most part (can't wait for any axis ones from him),
Spent most of my time on the spits before getting a little bored.
Used mitsu's 20mm, for the mossie i went all mitsu as it needs to sound badass, With waffles as the overall base pack with adjusted 50 cals, puffy and tank shells,
My best advice yoss is to do what I did and mix and match what you prefer, I also have national check sixs for certain planes. If you have ample time away from playing online i'm sure you can come up something pretty neat.
