Depends on how long you want to wait and make babies. If you want them next season then your in need of an 08 or older female for the following season I would say a nice sized 09 should work. But the bigger the better. I mean hell you can just pick up a 2000+ gram female Normal for under 50 bucks and breed her to your pastel and get 50/50. But if you want morphs then your in need of a pastel, spider, pin or mojave.
