well considering that most i have seen for sale are w/c i dont think anyone can say if they are or not. ahile back i think it was camlon reptiles had some on ks they said the 2 w/c ones had typical w/c burm attitudes where the cb one they had didnt. so im guessing it would depend on the snake just like most other supposedly "mean" snakes.
perhaps someone here who has some will chime in on their experiences with the actual animals
