Super cinny, not so much.. Savannah's, yes.. A dark, low quality cinny is more likely to produce similar offspring. You'd want to find the lightest, highest quality cinny you could if you want to produce high quality cinnys and morphs with it.
Just look for the busiest, messiest side pattern, the thickest/longest back pattern, and the lightest or reddest, most cinnamon colored one you can find.
