An interesting technique that has seen very little MMA application, but I fail to see how it has any application to the dogfight position. You've glossed over the hardest part of making the technique work -- getting rid of the underhook. I fail to see how "cranking hard" with the whizzer is going to get someone to release their underhook. By definition, if you're in the dog fight, the bottom player has a significant angle advantage against you, since his torso is facing you, and your torso is facing the mat.
