slimslag:
I just followed your link and read through the Ellsworth (and other) contributions - an interesting debate. His style of writing is very much "elderly american" but, filtering that out, I think he's advocating what many of us here would call "point and power" for the approach to the flare; I thoroughly agree with that providing the aircraft has sufficient power and drag.
When it comes to the flare and hold-off the cause of balloons is simply lack of recognition that the aircraft is moving away from the ground, this cured by actively looking (not staring) further away once the flare has started and using peripheral vision to keep the ground "around your ears" - if the ground starts to move away stop the rearward movement of the stick (DO NOT MOVE IT FORWARDS, except maybe in a go-around) until the aircraft starts to settle.
