I would start out with an albino female, and when it gets close to breeding age get a spider male. By then you might even be able to get a spider male het albino or at least possible het for about the same price.

Breed that pair to at least produce spider het albino. Breed that back to the adult female albino to produce 25% chance albino spiders. Or if you can swing the spider het albino male produce them first breeding. The main thing is if you have to spend an extra generation growing up a snake you want it to be male as they are more reliable as early breeders.
