A new snake

[Voodoo]

I have had a ball python for about a year and have thought about getting a new snake. My python i have who's name is Voodoo is everything i could ask for in a snake. She has has never bitten or tried to strike at anyone. I have wanted a new snake for a while and now have the money and space for a new one. Now comes to my question what would be a good snake totake on as a second. I've looked at a few but was not sure which to get. The three im really interrested are red tail boa,a hounduran milk, or a emerald tree boa. The order i put the snake in are backwards in intrest of getting.

thanks for ur help

I would aprecciate feeback as soon as possible as im going to a show this weekend and which has all three of the sankes i listed above.
