From looking at what you have i would just get the pastels if i were you. I wouldnt pay more than $800 for the pair of them.
You already have 2 males (pin and mojave) so the spider would be kinda pointless. And the het albinos arent really worth the money anymore these day like they used to be. Ive seen albino males for as low as $280 and the het albino females are pretty cheap too. This is all just my opinion, do what you want.
