I fly A330/A340 and have flown A319 and I use option 2 provided all is stable. If there is a decel trend I might leave the thrust on a few secs longer. I do however believe we need to be promoting more Manual Thrust landings on the Airbus fleets. For the pilots who don't fly light aircraft outside of the airlines the speed control scan and thrust adjustment reaction is quickly falling by the wayside. I'm a firm believer in appropriate behavior and I don't advocate a manual thrust landing after a 13 hr flight in trying conditions, but on a nice day do it to keep your hand in. It might just save your bacon one day.
