From what Ive read the wobble is sort of random. It may or may not get worst. It also might start off bad and get better or it might stay the same. I havnt heard of anybody being able to accurately predict what will happen with any individual snake that wobbles. I only have 1 snake that wobbles and so far his wobble hasnt changed. He has a slight wobble when i handle him and a pretty noticeable wobble when he smells food. But it doesnt seem to affect him as he is one of my best eaters.
