My 7A was OK for IFR so I worked out that I could fly the glide slope at 100 KIAS down to 200' AG, cut the power, raise the nose and then deploy flaps when airspeed low enough. Did not need brakes on any runway long enough for an ILS. 100 was much nicer for flying the glide slope well and made go-arounds a lot nicer and safer, too. Delaying use of flaps until the runway was assured meant a much better go-around if that was needed.
For VFR landings, one notch was plenty. More did not allow slower speeds but did change pitch and airspeed. The airplane could not fly slower with more flaps but would slow down more quickly.
The prop was a Catto FP, btw. That made it harder to slow down than with a CS prop. So for a short field, more flaps would be potentially useful.
