Our 9 yr old has decided she wants a milk snake. I'd like to hear recommendations on which ones make good pets.

We've handled a few different milk snakes in pet stores before, but I honestly don't remember which kinds they were. Right now, based on browsing through some pictures, she is leaning towards a Pueblan. Is that a reasonable choice?

She is familiar with snakes since she has handled our BPs and corns since we got our first snake in '07, and of course will have our help making sure the husbandry and such is correct. We also know that baby milk snakes can be flighty and may musk and stuff like that, and are prepared for that, but want something that will settle down as it matures.
