you can outscissor the spit14 one time, if the spit14 has any brain, he will yoyo up and come down again at you guns blazing, since you cannot pullup worth sh*t even with max trim in the A8 you can not follow him anywhere since the A8 has the worst possible E retention in the game, you are out of options except roll at the deck.
Well if you meet the low-time spit14 or any plane that think high yoyo is a new drink, you might have a chance.
Best chance is if you have 350+ mph and can dive to 450, spit lock up in roll.
