I'm still learning about the breeding aspect of ball pythons but in my humble opinion I'd suggest getting a male spider for your pastels. That way you'll be able to make bumblebees!! Or if you have the money you could spring for a bumblebee right off the bat to make more bumblebees, spiders, pastels, normals and MAYBE a killerbee. Don't get an albino unless your pastels are het. albino because the albino would have no visual effect on the offspring because it is a recessive trait. Good luck!
