how can one out-breed more than what's been done already. Who do you know that has bred spider x spider? I've never seen a spider that didn't exhibit the trait to some degree. Maybe it had the full on wobble, or maybe just a slight head tilt while crawling but they all have it. Perhaps the hundred or more spiders that I've seen over the last few years isn't a large enough sample to say beyond a shadow of a doubt, but I would bet that if someone looked long enough and knew what to look for, they would all exhibit the trait from mainly extremely minor to the occasional "spinner" (not the spider x pin combo).
