Dumeril's Boas/Carpet Pythons/SD Retics?

[RR - Mackenzie]

I have been looking for a snake to add to my collection (I won't be getting it for a long time, I just want to plan and research), and I seem to like the Dumeril's Boa, Super-Dwarf Reticulated Pythons, and Carpet Pythons the best!

However, because I am such a complicated person , I want one that is laid back, sweet, docile, nice to hang out with, and just a good snake all over. I would like it to be around eight feet (male or female), and not a thousand dollars each.

Which do you prefer? Which one do you suggest?

* And for Dumeril's Boa owners... Does that 20 pounds of muscle scare you?

Cheers (again),
Mackenzie

I would like one that has the personality most like a ball python (my ball python is such a sweetie!), but I want it to be larger. Small snakes like corn snakes freak me out (they are so tiny!), and I've always liked bigger snakes, I just don't want to jump into actual Reticulated Pythons and Burmese Pythons... I just want a large snake that is sweet
