My vote goes to the dumerils. I have 1.2 and want more. They are great snakes to handle. Also I seem to remember seeing an ad on kingsnake of someone selling dwarf dums that would fit nicely into a rack system there entire lives. Idk much on them other than what the ad said though. Imo dums tend to grow slower than your average rtb so you could get away with a 41 qt tub for about 3 years on a male and maybe 2 on a female and since they are ground dwelling they don't need the additional height like a rtb. Either way you can't really go wrong if you want a nice boa. Hogg islands are very pretty and I'd like to ad one to my collection but I can't seem to find one that I like when I've got the $.
