For me, the CSAT's TO-199 is the best jet, just because of her acceleration, but dont forget a paveload which is mostly indentical with the A-10 equivalent of the NATO untis in ArmA.
AFAIK, the A-143 is the CSAT jet. The A-143 Buzzard is what CSAT flies in MP.
Ah yes,, I had forgotten about the Neophron. I rarely see that thing flying about. Ill post a video I shot of me flying the Spitfire/Hurricane on Altis using the "theFEW" mod for ArmA II WWII.
