Hey Wolf, can't help but notice, but why do you have such a cynical view on those breeding spiders? You're making a lot of assumptions and generalizations that could offend a lot of breeders,

No one wants to give up hundreds or even thousands of dollars a year by retiring a spider breeder due to wobble.
I'd bet anything there are a proportion of breeders who are trying to rid the wobble from their own lines by holding back only non-wobblers, but are still breeding their wobble spiders to produce offspring for sale.
Where are you getting this from? You make it sound like the majority of spider out there for sale are defective and the people selling them are trying to stick it to the buyers...I'm sorry, but while some if not all spiders might exhibit some funky behavior, a very small percentage of spiders produces out there spin to such a degree that would prohibit selling them.

Do you own a spider?
