Well let me ask you a few questions. What are your breeding plans with this Het Pied Female? If she doesn't prove out, do you have other co dom males that you can breed to her so that she does become a good part of your breeding stock. By the time your female is quarantined and cooled she will be probably 3-4 months older, and if those lighter females are 08's they would be ready to go. You don't just buy a breeder female and throw the male in there, so really think about it.
Honestly just buy a 100% Het pied so you KNOW you have something, otherwise you have to have a backup plan for the normal. Personally i have both normals and hets, but i will NEVER buy a 50 or 66% het unless i think as a normal it will be awesome and may do wonders. On a side note, Boas and Balls is awesome!
Also never purchase a 100% het on the internet unless its from a guranteed reliable person. I bought my hets from a breeder friend and i've been to his place and i've seen his set ups and the parents and all his snakes, so i trust him. How are you going to be able to trust someone you've NEVER seen, or ever met and even if they do have "paperwork", whats to say its really theirs? Just wait man, i've seen TOO many people get ripped off cause they thought that 100% het was such a good deal and because it was double het for Albino Pied, they had to buy it. They never thought to think that $500 for a 1800 gram female 100% Double Het Albino Pied is worth maybe 5 times that if not more.
I'm not trying to get you down, just please do your research and remember, paperwork really means nothing so spend the extra cash for a trusted source or go and see it for yourself.
