I only have two with the spider gene in my collection, and neither has a bad wobble. The spinner in the picture is worst when she's excited, such as when feeding, but it's still not bad and since she readily takes f/t it doesn't matter if she gets a bad hit on the rat because of it. The other has even less wobble.
I would feel bad if I produced one with a bad enough wobble that it had to be culled, just as much as if I'd produced a badly kinked or otherwise deformed baby that couldn't survive.
