are you trying to make money or are you trying to produce cool looking stuff

the recessive animals are more pricey but they're more rewarding (their hets are expensive normals, and the ones that show the trait are very pricey animals)

double co-doms make some super cool looking things so i would also suggest that

can't go wrong with a bumblebee - anything spider related is always AWESOME

bumblebees / pewters / mojave combos - all good
