It is part of the problem that causes wobbling, head tilting, stargazing, corkscrewing, etc...

I have 1 male Spider and 3 females...none of them show any signs (although I know they have the problem). The second youngest did have a slight wobble but it seems to have gone away.

My 5 month old Bumblebee only shows a very slight wobble when feeding.

My 5 month old Butterbee shows a moderate wobble when it's feeding time or she's excited.

I've hatched several Spider clutches and have noticed some slight wobbling with some of the babies. Maybe 25% at most? Probably less than that as I'm just guessing.

And I don't even consider head tilting as an issue as I've seen other BP's tilt their head in a similiar manner as Spiders...I think I may have a slight head tilt myself...and it's never caused me a problem...
I think the term "wobble" is just a general umbrella term for any neurological symptom displayed by an animal with the spider gene. Yes, there are spiders that do not wobble. Instead they have very slight variations of the neurological disorder like head tilting or not being able to right themselves right away if turned over (my male does this on occasion). ALL spiders have some sort of neurological disorder. How much is shows, varies.

The problem is, you have people that have these spiders that do not wobble (instead they have the variations of the neurological disorder that are not as noticable) and advertise them as such. Newcomers to the hobby that don't understand that a head tilt is still a neurological problem, will be more inclined to purchase spiders from that person that has "no wobble" spiders. And then they are disappointed when the offspring of that spider throws wobbly babies.

Again, ALL spiders have some form of a neurological problem. You may not see it as it could be the slightest head tilt, or it could be as bad as corkscrewing, but it's there. It might show up right after hatching, or it could show up in the last year of life, but ALL spiders have it. And a spider with a slight head tilt can still throw a spider with a corkscrew.
