I would look into a pewter female for super pewters.
If the cinny gene passes on to any of the young you won't get anything with killer yellows, but you could start some long term projects by getting a pied female and working towards pewter pieds or an albino for an albino pewter.
You could also get a super pastel female (or even just a pastel female) and have a shot at more pewters, sterlings (super pastel cinny), super pastels, pastels and cinnies. For killer yellows, pastel yellow bellies can be really nice as adults or fireflies (fire pastel) are amazing. Pastel spotnoses also seem to be pretty yellow.
I'm partial to the lesser cinnies, butter cinny crosses after seeing Crawly's Mom post her's. But those aren't very yellow.
I suggest playing around with this to see if there is anything that you are really interested in.
