I'd choose a pastel female and/or a mojave female.
If you go the pastel route, you can breed both males to her. On one hand you get super pastels, the other hand you get bees. Both are good solid sellers.
With a mojave you get Pastaves and/or mojave spiders.
Obviously, if you can afford both females that would be the way to do it, you have the chance at producing 4 stellar morphs.
