WOW, that's pretty intense. I have a spider with next to NO wobble, I have yet to see even a head tilt. The "Cork Screw" deal, he has that, but a very MINOR case. Everytime I see vids like this I am Glad I got lucky. I agree with most, if I would of seen these extreme cases before getting him, I'd probably have stayed away.
Hopefully this year he father 2-3 clutches of Wobble/Cork screw- LESS babies....
I have heard also that after breeding they can develope a more noticable or more sever then "normal" wobble. I have yet to see it in person, but heard of it a few times on here I believe.
I think this morph is a Great looking snake, but as far as a new owner wanting one and being worried about the neurological problems....You have to just Love them for what they are, and deal with it accordingly. I wouldn't get rid of my spider for anything.....
