banana flipping with LP's

I was goofing off on the robot and tried a couple of banana flips with my OX LP's.  I was surprised when some of them went in.  I later tried it in a match on short backspin serves to my forehand and went 2 for 2.  I haven't worked on it since, but am thinking of developing it as a shot.  Has anyone else tried it?

It's relatively easy to attack backspin with long pips. There are two basic ways: either a regular drive (which would include a banana flip), or just bump the ball aggressively as if you were blocking it, and it'll go out aggressively with the incoming backspin now outgoing topspin.
