"I have several ATB. Some usually the CBB are very easy to handle and no worse than my other snakes. But others draw blood almost every time. Still love them"

Very well said. Basically, your best chance at finding a nicer temperament in these animals is one that is CBB; preferably for more than one generation... but any of them can be little heat-seeking missiles! :D
