Spider BPs: Wobble?

I heard that Spider BPs can sometimes have a wobble. Can someone tell me a detailed answer of the wobble (Wobbling their head). I heard it's a mental disorder that only the Spider BPs can get, and they cannot stop their head from wobbling. I don't want to purchase a Spider BP if it has a bad wobble..

Some have a slight head wobble, some roll their entire bodies in circles. You never know. Some can appear to be very slightly affected as hatchlings and turn into train wrecks down the line or vice-versa. Some people believe there are spiders that don't wobble, but I think it is becoming more and more accepted by big breeders and home breeders that they are all at least a little tweaked. I personally won't breed or keep them. There are TONS of previous posts on the subject if you do a search.

Some say all spiders wobble. Some people say their spiders don't wobble. Some wobbles are very very bad some say it is hardly noticable. It really depends on the indivudal snake. I have a baby that wobbles only a little. Make sure you ask if/how bad the wobble is when you buy. There is a LOT on bp.net about the wobbling spiders. Search the posts and you will find them. Good luck and just be careful when you buy.
