PAPIs are Precicion Approach Path Indicators, and therefore are not what should be used to land a light a/c in VFR flight. I was taught to keep the picture constant, and 'drive'it in, crossing threshold at 5kts above touchdown speed, aiming for the numbers, and touching down just after them due to the flare. By landing at the start, I do not wear out the brakes by standing on them to make the first exit. I think a lot can be said for the mil. oval circuit for ease and awareness as well.
