Agree on the Teflon - nothing ruins your landing more than pulling back, nothing happening, then whoosh! the yoke unsticks and the nose shoots up.
Beware the last stage of flaps, too, on the Hershey-bar style wings (i.e. not the Warriors): rightly are they known as drag flaps. I remember an instructor turning white when I selected full flap on final to Le2k in a Cherokee 180 - he said afterwards that he'd had bad experiences with students before doing that, not realising the airspeed was decaying rapidly, and he'd been expecting to have to swim for it... Fortunately I'd flown that ac plenty of times and knew that a handful of power is required if you want full flap. These days I wouldn't bother with somewhere as big as Le2k, but in those days I flew by the book more.
