I want to get a snake soon but i have been intensely debating which to get.

I am not new to herp keeping, just to snake keeping. I have a 50gal tank setup waiting for an inhabitant.

I originally had my eyes set on corns but since theyre a dime a dozen, i was wondering what are some other good beginners?

I'd prefer a snake to be reluctant to bite. This is very important to me.

Ive made up this list so far with optons and their negatives:

Ball pythons, stopping feeding behavior
Womas, nippy and painful bites
King/milksnakes, nippy
Pine/hog/bullsnakes, hard to find (hogs are venemous?!)
Rosy boas, nippy
Sand boas, hide under the sand all the time.

I know there is no such thing as an animal without flaws, however are there any options that any of you would recommend?
