Cloner with waterfalls or flooming... Anyone uses them?

There are beautiful cloners in use by hydro growers.
Often DIY and often with sprayers, airstones or venturi.
But are there also growers who use a cloner with waterfalls or the principal of flooming?

Sure, but its just a different way to do the same thing.
I've grown clones in just a bucket of water with an airstone and a few different cloner setups.
As long as the waters moving and you're getting enough aeration it doesn't really matter how you have things setup. Not going to be any benefit over any other method though.

I know how getting DO in your water works.
But I am curious who actually did it.
And what their experiences are.
