Ditto on everything you said, I use and teach the same methods all the time.
Sometimes I see a pilot bouncing his plane off the runway consistently and I'll go stand behind him and whisper in his ear " on your next approach don't let the plane touch the runway, concentrate on keeping it off the runway and it will settle all by itself " and then I usually hear "OOOH, that was neat".
I've worn a quarter inch off the tail skid on my new World Mach 1 trainer, great airplane.
