He kept climbing with me, so I decided to engage. I didn't dive on purpose, but when I lowered my nose for a shot, it went into a compression dive. Maybe I don't know the Niki that well, but I didn't think they could sustain that kind of speed in a dive and survive. I didn't expect him to follow at those speeds. I consider the Niki a low-medium alt fighter. I guess I know different now.
