My Mojave spider, who happens to be on my arm right now, is a severe wobble case.
He hangs upside down. He eats perfectly, sheds great, but he'll rise his head as if he's periscoping, but then he'll flip his head upside down to watch stuff, rather than keep it upright.

As for his deposits, he tends to do it in his water and then dunk his head in with it. Other than that, he's handled regularly but still acts as if he's just seeing me for the first time every time and hides his head for a few minutes before remembering who i am.
