We're kind of getting off topic. I'm asking what you all think would happen if a new line of spider was found in Africa and it, along with it's offspring didn't show any symptoms of the wobbllies. It's unimportant who's selectively breeding the current line, for the sake of this thread.
I also love spiders, and mine definately shows a slight wobble sometimes. I am still breeding him, as I believe from what I've read that it isn't seperable from the spider gene in captivity today. I still see it as a defect if it is in fact a nerological disorder. They can eat and reproduce fine, but I'm pretty sure the derma ball can also thrive and reproduce, and I agree with a lot of other people that the derma ball is a defect. If there was a new line of spider that didn't have any "effect" I would definately replace my current breeder with one from the new line. I think a lot of people would, but there are so many people who have so much invested in spider projects that I don't think that it would be feasable for many to just retire the old line.
