Dude, this is coming from a guy who has seen the damage native snakes inflict. Buy something only mildly toxic-like a vine snake. Their bite is nasty but at least you won't lose a hand. Anyway, the two snakes you mentioned are super aggressive and you couldn't do much with them except feed them. I'd stick with the snakes that you can handle at least. vine snakes are cooler anyway. they're like a green snake with attitude and and odd nose.
