You fly the Mustang as it should be flown. You appear to have good SA as well.
No, it's not 'at risk' fighting, but I would not expect that out of a P51. When you do see it (what ever happened to RWY anyway?) it's a scarey sight and very unexpected.
Midnight, what these guys want you to do is break every rule you have set forth for flying the P51, and survive it anyway. That's the only way they'll ever have a chance of besting you in your plane. Then, they can strut and parade after they get you into a 30v1 fight and somehow put the extra bullet into you that claims the kill. It doesn't matter how amazing you are on the deck, or way up high, either. There's no convincing them that they're wrong.
BTW, nice back shooting on those first three planes. I love that!
