It sounds to me like you're getting into breeding because you love the animals, yes? Well, what do you like? That's what it really comes down to. What combos do you really like? What base morphs do you like? Get what makes you happy and what you're going to enjoy because they are going to be with you for a long time!

For 1k you could buy a pastel male, cinny female, spider female, mojave female and even some cash left over.
I like this idea . They'd be hatchlings, so it would probably be a couple years before you saw any babies from them but in the mean time you could breed the pastel with your normal girl and hopefully get some more female pastels to hold back.

Good luck man!
