The right way?

Back in the training days of my PPL I had the bad habit of landing with a
some throttle still in (instead of power idle) and with little pitch
attitude. But the landings were always pretty smooth. Now I do what the
instructor taught me: cut off all power before threshold and raise the nose
wheel well up in the air during flare. In the final part I get the stall
warning tweet (as the instructor told it should be) and the result is a
somewhat rude main gear contact if the timing of the flare is not perfect.
Sure the plane stops in very little space (we operate on a 2000 feet
runway), but I get the feeling that I don't do it the right way since very
seldom I grease it out as I did before. Is just a matter of refining the
technic or am I missing something?
