Well, I suppose I'll put in my two cents on the preferred spider traits...even though this thread is pretty old.

I personally like high white, and a dark pattern on gold. The lighter gold the better! That's why I have her:





As for wobble, she started out with the slightest head shake and would 'bend backward' while going up her tank sides (i.e. head upside down like a backward roll). It was kinda cute to watch. But now, the wobble is all but gone. There's only the slightest tremor when she lifts her head high or when she's excited.
