Spider wobble in full effect

My male spider wobbles--not as badly as the one in the vid, but he gets himself into some strange positions, and often misses his first strike at prey. He gamely turns right around and tries again, and generally hits it on the second attempt.
He's a great eater.

He was bred, and his offspring have run the spectrum from no noticeable wobble to a wobble about as bad as his. I suspect that extreme wobbling is actually relatively uncommon.

I have never seen any sign that he is distressed by his apparent inability to reliably tell which direction is up. He eats well, breeds well, and behaves in all other respects normally.

Unlike mammals, reptiles don't just carry on with eating and reproduction when something is wrong.

My smaller spider male has just started showing signs of a wobble and he is 3 years old. Ironically it was shortly after he took his very first F/T rat after only accepting live prey. Coincidence? I may never know lol.
