but I occasionally hear the stall warner go off just before touchdown
I'm firmly in the "land as slowly as possible" camp, but I learnt by experience, that is a good idea to brief your passengers about the stall warner to avoid scaring them.
172s balloon like nobody's business if you come in too fast
I once had to do a full-throttle, flaps-up ILS in a 172, to assist ATC in traffic sequencing (in VMC). It took a VERY long time to slow down and I had a tendency to try to flare too soon and consequently balloon. Luckily, it was a 12,500' runway.
