When I used to fly a Pitts regularly, my instinctive reaction to the rare occasions when the world started spinning in unintended ways was to close the throttle and reverse whatever control inputs I had in. This stopped the world spinning every time and so I never had cause to work on refining the recovery or finding a back up.
In reference to airliners I think that a pilot who is on the ball enough to be able to competently and efficiently recover from a UA probably wouldn't have got into the situation in the first place. Assuming that a pilot has allowed a UA to develop we must also assume that their skills are most likely average at best.
