I would invest in a pair of het pieds or het clowns if you can swing it. Recessives may take longer to produce, but there is so much combo power in them.
If you are looking for a co-dom, I think lessers produce nicer combos than mojaves. I loved the mojave/spider as a baby but boy it did not hold it's colors well. Cinnamons make some nice combos as well. With what you have you could make a cinnabee or a pewter.
Or go for a fire, they really brighten things up!
Heck, even albinos are affordable now. You could pick up a visual & a het with your refund.
Adam is awesome to talk to about trying to figure out different routes depending on what you want your breeding future to be.
