We operate our 320/330's from our own SOP's with the Airbus SOP's inserted as needed. On every turn-around flight we do a quick align as most have mentioned to zero out the G/S or any errors. We will do a "securing" C/L when we have about one or more hours of a crew change. This ensures that they do the initial overhead checks and fresh align of the IR's. We are not perfect, but it does work.
Cheers...
