Under what circumstances do you think you would wish to select Alternate Law and which flavour of Alternate Law do you think you would like?
Since most of the uncommanded A320/330/340 flight path excursions which have been reported seem to have involved incorrect sensor information being faithfully acted upon by Normal Law protection features, the minimum necessary action to countermand such spurious events before an extreme event is reached would perhaps be appropriate - so probably Immediate Alternate 1 ?
Far better though to eliminate any source of sensor failure in the first place.
