I'd be interested to find out if the HG womas wobble. I think those threads are all about "regular" womas, so I think it's safe to say that many of them do have a wobble similar to spiders (though not as consistently).

Tim Bailey mentions that his HG woma doesn't wobble, though that is of course a very small sample size. We do know that the pearl (homozygous HG woma) has profound neurologic issues, so even though womas and HG womas are totally unrelated, I wouldn't be at all shocked if some of the HG's wobbled too.
