Taking another look at the "spider wobble"

[snakesRkewl]

I have an 08 male spider that showed very little wobble if any till he hit 8 months old.
Now he's a full blown corkscrewing wobbling wreck.
He's always been in tubs since he was a hatchling, has never been stressed as far as I know, has always eaten and has rarely missed a meal since he was a baby.
