I guess it depends on what you want to make. I say go for the spinner. You can get more combos w/ a 2 gene male.

Mojave + your two females = Blue Eyed Lucys, Pastaves, Mojaves, Pastels, Lessers, & Normals


Spinner + your two females = spinners, spiders, pastels, lessers, pinstripes, king pins, lemon blasts, spinner blasts, bumble bees, lesser bees, and normals.

It takes less time to grow a male to breeding size than a female. So you could probably breed that spinner at the end of the year if you wanted.
