HN39, you asked "Using full rudder would help getting the nose down. You didn't forget to extend the flaps on the other wing to permit rolling it back to wings level?"
Um, I'd rather envisioned retracting the flap that was temporarily extended if the plane gathers too much speed to safely have flaps extended. Regardless, the concept is that once it was broken out of its "spin" you'd want to return to a symmetrical configuration. Otherwise you simply buy yourself new problems.
