Mamushis are nice snakes ,Alittle snappy but easy to control. Be careful about treating them for parasites they are prone. Also I really dont think that useing a non venomous for practice is much help ,it all comes down to being as careful as possible education of the snake along with fear and respect is going to be your best bet. There is know substitute for the real thing. Always be aware of the fall out if something goes wrong. Chris
