If you're flying an A320 in a gusty conditions, I (and my company/Airbus) suggest Flap 3 rather than Full. Same with a 321 to a lesser extent. Responsiveness in roll seems much better with Flap 3 - without it you'll sometimes find that max sidestick deflection is not enough and that you want the aeroplane to respond quicker than the computers will allow. If you're "stirring it" on approach, take your hand off for a few seconds and remember the aeroplane is trying to fly what you asked without too much help!
You'll find the sidestick totally natural after a couple of circuits and no trimming needed - like CWS on a 737. Just point it where you want it and let go. The FPV is one of the best things since sliced bread (not as good as Sky Plus, mind). Just put the aeroplane circle on the horizon and you're level, regardless of speed.
Enjoy!
