I run all deep 10 frame equipment.
Queen excluder is a tool in the beekeeper toolbox. It is used to control where you want her and where you do not want her. In doing so, the work can be better managed, more efficient = less work. The QE puts the beekeeper in control of how the hive equipment is organized. Without it, the hive is out of control and thus so will be the operation of the apiary. Unmanaged, uncontrolled results are highly variable.
To the question of doubles vs singles. The answer is: both, each at the right time of the season. My hives are doubles through spring for population growth. When target population size are near, she is pushed into and confined to single a week before the heavy nectar flows start. And she is kept down there for the rest of the season. This method maximizes early bee-power population and highest harvestable honey production, with least beekeeper nest work.
The timing of the move has to be on point. Push her down too early and she will swarm. Push her down too late and you will miss out on a sizeable amount of the honey flow.
Hope that helps!

Thanks for the good explanation HoneyPump. A couple questions further; When she is pushed down, what is done with the top brood box? I am guessing it is left in place, allowing for all larva and brood to hatch. What is after that for this box and frames? Are they left still inplace, becoming a honey super right where it sets?
When you say 'pushed down' is there a certain method you use to push her down or do you simply go into the brood area, find her, and move her below adding the QE?
(Manually moving her would be my assumption, but just an assumption, I do not want to miss something here, good stuff!)
