To the OP:
People have cautioned you as to the potential for kinking with SuperCinny but no one has mentioned that with SuperButter you have the potential for bug-eyes.
Also something to consider, with SuperButter you will very likely end up in a position where you have no clue what other genes the animal may be carrying. Is the white snake you get from a clutch a SuperButter SuperCinny Enchi Pastel GStripe Hypo or is it just a SuperButter??? Do you want to hold it back to breed it out to find out? If you want to sell it then how do you market it?
That is the calculator from MorphMarket. My only caution with it is that it does not do well with a couple of the heteroallelic supers (BlkHead/Spider... Cinny/Huffman...) but it is a lot more friendly than most of the others
