IMHO, the "double flare" technique will scare the people you fly with and is a sticking plaster to a bigger problem. I would also caution against the technique that you will see on the line at some point of just wallowing in ground effect and closing the thrust levers at touchdown.
The Airbus FCTM teaches the best way. Trust it. And be happy with a plop into the touchdown zone on the centre line with nothing broken or out of limits.
