Well for one, I agree with you decision to breed your pastel to the high blush female. I really like a Ball with high blushing and flames. I'd think that you'd also choose based on eating habits, sheds and weight. Spiders are clearly selective breeding in my opinion. Pastels too, though some don't agree with that I'm sure but a very dull pastel is a waste.

Cinnamon are my favorite, when they're black I'm not that found of them but when they are deep rich brown (not light) they are stunning.
