Got ya, OK so I think I know what you are talking about with the "corkscrew". I posted a youtube link to a video with a wobble spider/pinstripe. They just do these movements out of the blue? Or they are attempting to do something and cant, meaning their movements are hindered and it causes the wobble? I dont have a spider, just a norm. I am only trying to understand what this is and why it happens, also if I can prevent my BP from getting the wobbles.
The movements do seem to come "out of the blue". I don't think the wobble hinders movemant or anything else for that matter. Like Freakie frog said, 10 out of 10 will wobble, meaning all of them to some degree, so I don't beileive you can prevent wobble.
