A triple/quadruple codom/dom morph. Super x codom/dom morphs. Some unknown morph which you want to test. Yeah that's about all I'd pair with a normal. But that's me.

Just get a nice pastel or something het for something. That way you can produce more pastels for a super later, or you could try to produce a hom for whatever trait.

Although... normals seem to often be carriers for the daddy gene, so a lesser/butter would be a great choice.
