Most spiders eat just fine even with a train wreck wobble, most likely what you are seeing is brought on by stress. If I read correctly you have had this snake for 2 months and not handled very often, she probably just got a little nervous and got to spinning. Mine seems to do this too, she didn't wobble at all according to the breeder (who is a friend, he wasn’t trying to just make a sale) when I got her home she stated to spin in her cage. I have found that if I pick her up and point her to her hide she will stop, crawl in and relax. I have noticed that her wobble is actually worse when she is actively looking for food.

As for breeding I understand that it is different to see the wobble in person, rather than just reading about it. It does not seem that the severity of the spider parents wobble dictates the severity of the off- springs wobble. I wouldn’t worry about it, just make sure you only sell to people who know about and understand this issue.
