I've been using the XXX flare for over 10 years now and never had a hard landing or single bounce.
You can read about it in my new book titled "The XXX Flare." Only $19.95 at all good book stores or at your local flying school.

On a side note, spoke to a CPL recently whom until about hour 120 of his CPL course used to flare at Moorabbin based on his indicated altitude, at which point he went out for a nav then came back only to find that it was over-reading by around 50 ft so his landing was very hard. I can't believe he made it into his CPL that far and lived.
