RAM, D9 (MW50) acceleration should be better than A5 and even better than Spit XIV, and high speed, and, of course, high speed handling, IMO, is the most important thing for this arena. For example, 109G10 acceleration and top speed are superb, but in a high speed duel, P51 can fight them without problems. Spit XIV can negate 109G10, ok, but not the 190 series. And dont try to compare 109G10 with 190D9, 109G10 has just no chances (stalemate or dead). I thought you knew what 190 was able to do ...
