i think mystere 4a should down to 8.3 and below, it has a poor energy(mostly speed) performance
And the br8.3 Vautour IIN is not a bomber,it’s a intecepter with no A2G loads
The 2N has bombs, it’s the late variant that doesnt.
The Mystere is doing good at 8.7, why not 8.3 but lower would be unfair for other fighter who has no AA missiles.
