I've had Burms and Retics and currently have a 7' Snow Boa but I have never used hides for any of them ... they've all been extremely calm and tame .. maybe I got lucky each time? Who knows...
Thing is the when I got my first hatchling Burm the breeder strongly recommended that I never give him a hide as he argued they're so confident and inquisitive they do better without them in captivity... no predators etc ... Oddly enough the Retic breeder said the same thing ..plus he said you don't want a 13' killing machine shooting out of a hide coming at you ...
Anyways ... just my take on things..
