This guy had you twice, but instead of working the roll-rate he went into the negative G thing. My preferred is the barrel roll defense. The 190 being both fast and great acceleration those on the 6s bore in for the kill. I begin to barrel roll them, they keep boring in, trying to roll with the 190 to no avail. Then at the right moment a good hard turn, another barrel roll and they overshoot.
Completely different story if they know what a 't-h-r-o-t-t-l-e' is. Fact is, if something gets on your 6 only stupidity on their end will get them off. As Save says, the 190 only has the roll but done right with a weak-minded adversary you should be just fine.
