Are you looking for answers as far as collecting or are you looking for future breeding? Also I take it you are talking base morph!

Collecting would go like this for me:
1. VPI Axanthic
2. Albino
3. Pied

If you were looking for something to breed then more questions would come to mind. Are you talking hobby breed or business? Are you limited to three snakes or three types of genetics?

If your doing hobby breeding you got the time to play with ressesive morphs all you want. If you are doing it as a business then you will probably want at least one dominate/co-dom if not two and at least one ressesive to play with. Also you want to make sure you get at least one pattern and one color morph.

These are just my opinions!
