There seems to be no escaping it, any spider or spider combo will have a wobble of varying degrees. Some are very slight, almost non existant, while others can be crazy cork-screwers or you can get anything in between. I had a spider that would only wobble when he smelled food and when he struck it was always up and back over his body. It didn't take me long to adapt to his style and start offering rats above and behind his head.
Not so random...in most Spiders but doesn't affect them IMO....I have a female that wobbles and corkscrews but she is my best eater...fastest grower and I will never part with her...
that is a very nice Spider you picked up and if every BP ate like Spiders we all would get 8 to 12 eggs every clutch
