That's a great question, I've wondered why more ppl don't work with them myself. I think they just aren't as dramatic base morph as the other BEL complex mutations, so ppl don't give them much attention as the others. However, after seeing how they can make some amazing designer morphs when matched to the right genes, I think we will soon be seeing them a bit more. I would love to find a Russo Spider aka "Flame Bee" female after I saw NERD's Opal Diamond Spider.
