I've tryed large enclosures and had balls go off feeding and they were housed with hides..
Now since i've kept reptiles for many moons and have a freind who owns a rep store and breeds them i've met several breeders and dealers over time and all will confirm my findings.
I dont want to debate it but if you find something that states a bp should be housed in something bigger then a 30g std please post it with a link i would love to read it. .
