The sharp aileron input seemed to be the basic recovery manouver as taught to me but speedbrakes seem to be much more effective.

With the sharp aileron input, as said above, you did it into the rising wing. So choose a wing and then each time it is rising, apply aileron input quickly and then back to neutral. You could screw it up though. If you look at the ADI and after having chosen a particular wing to apply aileron against, you do it 180° out of sync because you mistook the rising horizon on the ADI as the rising wing. Oops.

We practised it in the sim but did it in the real aircraft on a post maintenance check. Yaw Damper off and then a small kick in one direction of the rudder starts the cycle. Real plane seemed to handle like the sim.

Here is the kind of strange part. Initially the wings tended to dip more or less equally on either side of wings level(call it the neutral point). But, after some aileron recovery inputs you can end up with a new neutral point such as, for example, 15° right bank being the new neutral point and equal wing dips from that point. Happened in the sim and on the airplane.
