When I purchased my spider there was no mention of wobble. I didn't even know it existed. He's about 2 years old now and I'm only now seeing a ever so slight wobble. It is barely there. The wobble is ATTACHED to the gene. The gene causes it. If you have directions to build a bookcase you cannot use those same directions to build a car! The directions tell you to do one thing and one thing only and in the case of the spider gene, it causes both the color/pattern change as well as a neurological problem that is the wobble. The gene won't tell the organism to do anything else. You can't breed the wobble out of the spider gene. We can attempt to breed spiders that wobble LESS but they will always wobble to some degree.
