But would you know when you get BEL Spiders? Personally, if I had a White Diamond BEL, I would probably either get a lesser or super lesser or another het russo or White Diamond. That way, you'll get your clean white BELs and you'll know the genetics behind it. I don't know if het russo x phantom has been done, but I would be willing to bet that that pairing would also yield some clean white BELs
Hope this helps
