If you find G. pulchra slings, PLEASE for the love of all that is cold-blooded and good, let me know!! I think I'd sell a kidney..
I have a B. smithi and so far it's been nice to have. I also have two G. aureostriata slings, one is 2" and the other is 1/2". Both very easy to care for and easy to handle. I also have two B. albopilosum, and they are just dolls. Not flighty at all, but are easily overfed as slings and it's possible to kill them(mine get fed once every 1.5 weeks or so and they do fine). Also have a Haitian Brown, but yeah...THAT one's fun to deal with, hehe.
