I would say its a guessing game. Thats one thing though that you dont want her young to carrry. The wobble though could decrease with age also though. When I had my spider male he didn't have one at all when I got him as a hatchling but at about 6 months his got real bad and he ended up dying from sever neurological disorder, he couldn't stop flipping on his back so I had to have him put down at the vet, couldn't leave him suffering. So with spiders you truly never know what your going to end up with.
Kind of hard to die from a sever neurological disorder if a vet puts the animal down. That is putting out erroneous information by making that statement. The Spider died because you didn't want it any more. I have seen serious train wrecks that do just fine.
just my
