I have not seen evidence of a wobble in the '06 spider that I purchased from Adam last year. If I recall correctly, she was a hold back of his and he had not seen evidence of a wobble either.

THAT SAID, there are environmental factors (stress) that can elicit the wobble response. Maybe my spider isn't stressed Maybe she needs more stress-- wish the darn girl would breed

I know that VPI is now rating the amount of wobble on their spiders so that every customer understands what they are getting. I think that's a good idea; at least it's better than saying nothing
