I would also go with a pair of 100% hets. Or you can get a female het or a few 66% het females and when they are breeding size give them out on a breeding loan with someone who has a male albino. Then you can split the offspring, and will have all albinos and 100% hets. If you went with a 50% het male, you have a 50% chance of waiting and breeding for years just to find out you have all normals.
