Believe me there is no P40 smack down ever.  There are however, very excellent pilots that know their stuff.   I have plenty of basis for my arguement.  Show me as many charts as you want.  I know that Hurri 2C clobbers them all.  Why is that?  It has tater launchers and good ones at that.  
My point?  I guess you would have to find Dastrdly flying his 110 C against anyone doubting any validity in my arguement and ask them afterwards.
Anyhow, planesets have been a sore point in this arena.  Given the choices, I tell you right now what side I won't fly.  As good as AH2 is, it does not do the 50 cal armament justice.  The battles that we engage in are snapshot battles, seldom a shot long enough to give the 50 cal saw effect needed in game.  On the other hand, snap, crackle pop..... cannon round .... I'm down...... way too often.
