All spiders have wobbles. Now, only some have it bad.
But there are some circumstances that make the wobble appear more, and more severe that will go away once they're fixed.
1. Stress, they wobble a lot more when stressed (if it's bad, it gets worse, if not noticeable, you start to see it a little)
2. Feeding, sometimes can bring out the wobble in a spider morph.
3. Drop in temperature. Was it on the cold side when you picked him up? If so, how cold is it? This could also mix with stress making it appear all at once when no wobble was seen before.
If one of those things went towards the problem, then once the cause is gone (warm, in the tub, done eating) symptoms should go back to the norm.
Unfortunately, you'll never find a wobble free spider, ever, so either try not to be heart broken (You can still love the little guy/girl!) or stay away from the morph.
