I'm working with pieds, and the spider gene simply isn't my favorite pied combo. I admit, I do also feel pretty terrible every time I see a spider wobble. BUT... I might be lending out my axanthic female to a zebra bee project this year. That'll be my first foray into working with spiders.
I'm still pretty unlikely to ever breed for homozygous spiders. I've already got a lot going on with the pied projects, and I'd much rather sit and wait until we have more information about the health of the homozygous babies.
