My female spider is one of my favorite snakes I own. She's a little quirky and such a sweetheart. Her wobble is only apparent during feeding times, but other than that she gets the head tilt occasionally and that's about it. She rights herself immediately after being flipped over and doesn't corkscrew, and is one of my best eaters. She'll eat the largest size rat possible for her size in half the time it takes my bigger boys. I just love her, don't be afraid of the wobble. IMO, there's plenty of "traits" that people knowingly breed with and (depending on the trait of course) it usually turns out fine. A slight "wobble" doesn't concern me when there's a lot worse things that could be bred into this hobby...
