Rainboe is right.
I did about 5 minutes in manual reversion, on an air test prior to deep maintenance to get some trim measurements.
The sim was heavy in manual - but the aircraft is much, much heavier, probably 3 times the control loads. At 250 kt IAS, both pilots trying hard to roll (in the same direction, yes!) we managed about 5 or 10 deg/sec roll rate. I would not like to try an approach to land like that.
