Ormond and Harry (father and son) used single Lang brood chambers with q. 
excluders, and 6" honey supers. They used a lot of honey supers, and always 
added the newest ones right above the excluder. No doubt a lot of work to 
shift all those filled supers to add a new one, but they claimed this 
prevented swarming. They were in Santa Cruz, CA and I believe they usually 
wintered in one brood chamber plus one super, with the hives being wrapped. 
They were cautious about cool air and drafts in the hives. As I recall they 
experimented with things like 11 frames in the brood chamber, a la Charles 
Koover, but ulitmately did not find this to be practical. Another set of 
experiments involved grounding the queen excluders. You could say they 
really mollycoddled their bees. Their two books are written in an affable 
style, and make for an enjoyable read.
