I wonder...all this discussion about stalls and using rudder (or not) or ailerons (or not) during recovery.
Has anyone here actually stalled a large swept-wing airliner?
Is so, what were the results?

Having discussed this subject with Lockheed production test pilots, whom have actually intensionally stalled an L1011 during acceptance tests, rudder is never ever used to 'lift a wing' when the airplane is fully stalled, either in the clean, approach or landing configuration.
To use rudder to 'lift a wing' in the fully stalled condition, is to invite a rather abrupt up-side down condition, IE: inverted flight.
Not good for keeping ones breakfast down, me thinks.

Personally, I have completed acceptance tests with L1011 aircraft where we approached the fully stalled condition.
Rudder was never used during recovery...stab (the L1011 has an all-flying stab, unique to civil jet transport aircraft), ailerons and power, only.
No rudder.
