I have a normal female, and a pastel male that are just shy of being a year old... and while I have a ways to go yet for breeding them, I wanted to do some research in the meantime and find out what would be the best morph pairing I can do with the pastel male.
I really want to pick up at least another single gene female or maybe a female super morph of something, maybe a super cinny if I can find one affordable enough... I really want to create some nice morphs with Benny's genes, since he looks really outstanding for a single gene pastel.

So, my question is, what is/are the best morph(s) to pair with a pastel to create desireable morphs (and/or designer morphs too)?
