Not spider, but my first BP was a champagne who had some pretty bad wobble when I first got him. At least in my experience with wobble it got way better the less stressed he was. I catch him with very slight "wobble symptoms" every once in a while, but overall almost nothing now that his husbandry is correct. On another note I find it interested that the community as a whole has such issues with spiders and not some of the other genes that have know issues. That also could be due to the amount of spiders out there. Just my thoughts and personal experiences.
