I don´t fly it anymore... (because now I´m LHS of the next best albeit older type)
Same company as the cpt in the videos.
Actually flew with the guy once - he´s a training captain, but he lives and works (at least he used to work for Airbus) in TLS most of the time.
As for the x-wind technique on the fbw-busses, it differs from other aircraft, since you cannot fly crossed controls during the approach:
Keep the crab into the wind until ca. 50ft (and it starts to call you a "retard") and wings level.
In the flare smoothly pull it straight with the rudder, while possibly giving a little stick input into the wind if the wing starts to come up.
If you land with a slight crab, pull it straight before the nose wheel finally comes down.
Use the stick only to keep the wing from coming up, since you´re only using the upwind spoilers and thus creating drag and yaw into the wind again!
