When it comes to temperament of a big snake I consider the Burms to be the easiest (excluding Boa Constrictors which I really don’t put in the "Big Snake" group as Burms, Retics, etc.). I have kept Burms, Retics, Rocks, and Yellow Annies and by far the easiest to train and "Tame" where Burms.

That being said I always acquired a baby of these species and raise them using the "Hook Training" method. I personally think not taking that precaution and of course not having a second person on hand to handle them when they are big is risky.

But if handled correctly and respected for what they are you can have a wonderful pet.

Of course they all have their own personalities.
