I've never seen a spider without a wobble. I'm sure there could be some out there but from my own experience, they all have it. My bumblebee that I got a few months ago only does it when he goes to feed. Its almost like he gets all excited and starts shaking. He is very healthy and my best feeder by far!
I know there are some very serious cases of the wobble but then again, there are also retarted people born every now and again as well. Should we stop people from breeding too so we don't have to worry about another mentally challanged person born again? Come on, get real....
