The snap roll can spoil a Bish Spit's gun solution quick. If a spit dives on me while I'm... ummm.. "extending" in an A8, I like to let him close to 1000-800, then give the stick a violent jerk to the lower/right position (to pull you up and to the right). You'll enter an accelerated stall right away, and the engine torque will flip you over and to the left. So from the spits POV, you start a roll to the left, then freak out and flip to the left.
Uh oh.. that's the infamous FW flip-flop manouver - gaming, not acm.
