I was told that if I incubate at a lower temperature around 86-87 it will reduce the wobble where you will never notice it. Is that true???
Only because the egg might not hatch and then you wouldnt be able to notice the wobble. heh.

The wobble isn't really a static thing though either, watching my friends spiders grown up I've seen it come and go. Maybe it has nothing to do with age just the animal on that day I saw them was better or worse but I don't think that how they act for a couple of minutes in your hands is going to be a good indicator of their wobble throughout their lives. Just know its a concern, if it does concern you, going into the deal.

As was already said my buddies eat just fine. So it doesn't seem to bother them all that much.
