I am working with boas and am extremely happy with their progression. I am going to be adding a pair of Angolan pythons to my collection this year if all goes well. Chondros are wonderful and my Hunter is one of my very favorite snakes. But after talking to his breeder, I don't know if breeding them is for me - baby chondros can be very difficult to start feeding and can be quite delicate. Of course, what one considers delicate, another might find quite hardy - it's all a matter of perspective. Blackheaded pythons are awesome and much like womas. I prefer the blackheads. But you have to be prepared to have a very large python (some get bigger than the average BCI) and feed them a variety - rodents supplimented with chicks and even fish.

Just based on the little you mentioned in your original post, I would suggest bloods for you. Seems a logical step with what you've kept in the past and there's a huge variety in their colors and patterns. Just a thought!
