plus one for the crabbing technique, when i started 25 years ago my instructor said just do what was easier for me and what i felt comfortable with. Never mastered "wing down", it always felt very un-natural to me. With a bit of practice using the rudder to "kick off the drift" during the flare works fine every time and this method has the advantage that you dont need to do anything different when you get on to the big fast equipment. Its a bit risky to do wing down X-wind correction on a big aircraft with big engines under the wings...
