I like the breed with both idea.
Another option is to think about future breeding possibilities. Personally, the possibility of eventually being able to breed mojave x mojave would be more exciting to me than doing pastel x pastel.
But if it is a tough call for you, breed both! Imagine the excitement! And there's always the (very slim) possibility you will get a double sired clutch.
Keep us posted with your decision!
EDIT: No, it shouldn't matter which snake she pairs with first![]()
