I agree. Every one that I've seen wobbled to some extent. Some it was just barely, others it was more extreme.
And I don't think what they do as hatchlings is a good indicator, at least not in my experience. My female spider didn't wobble until she was about 6 mos old, she's now two and its a lot worst than before. Not extreme, but nothing like it was a year ago either. But other than that she's 100% healthy.
