Ok. You have the opprotunity to get a captive bred Retic, Burm, or Afrock. You happen to have a spare room that you have been converting for just such an occassion, and your spouse says, "Sure, honey, I think a giant constrictor would be a wonderful addition to our family!" You only have room for one, so you have to pick one of the above three.
Vote, and then post, with what you'd get and why.

I would get a Burm. I have never had a giant, and think it would be best to start with something that is not as active as a Retic or Afrock. Everything I have heard about them vs Burms says that Burms are more laid back, and are more likely to be content to just lay there, as opposed to always moving, like a retic. While I'm sure that an active baby retic is very endearing, an active 27 footer is not!
