Thats a good plan ...if you can get a Hypo female or two they are worth their weight in gold ...when they are big you can breed anything to them, but of course you have to wait for them to grow ..if you can get adults grab them and breed your Pastel to them to get Pastel 100% het Hypos ...and then when you get your Cinnie or Mojave breed them to the Hypo's as well. the other option is to grab a Yellow Belly male or female ... again the females can be bred by almost anything and add huge value ... or it you can get a nice male, which are dirt cheap at the moment (for what they produce) go find some nicer aberrant stripe & granite females and have fun ...you can get Ebonies, Super Stripers, Pastel Yellow Belly, etc, etc.
Good luck,
cheers, John
