Very similar in my XP. All the black rats I've encountered have all been albinos(I have one myself) and I have nothing but awesome things to say about temperment. Wafer is my calmest and seemingly "smartest" snake. Has never bit anyone and has similar personality trait to a boa in that he doesn't like going back in his enclosure. Him and my BP are my snake embassadors when I want to pull out a snake and show someone how awesome snakes really are. He also gives good neck massages.

I can't comment on their personality, but check your laws first. I don't know what you mean by "dfw" as your location, but it is illegal in most states to buy, sell, or barter a native species.
A positive attitude may not solve all your problems, but it will annoy enough people to make it worth the effort. ~ Herm Albright
