First off I have never understood why people ask this question. Get the snakes that you like the look of or that will be a means to an end for a project that you like. Also 7 males is not a good idea. I have a ton of males and half just sit around with no female to breed them to and they are another tub to clean and mouth to feed. Why dont you try getting a few females and 2 double gene males to start? It will be easier on you trust me. and your list makes no sense.
