I would say a ghost het albino would be really nice or if you can afford it a moonglow would be better (visual for anery, hypo, and albino). A snow boa would work, but they are a bit steep in price as well...and of course, another dh snow

Any one of them would have the potential for a great litter, but only you know what you can afford within the next couple years. The advantages of a combo morph that visually displays the albino gene is that all the offspring would at least be het for albino.
