It has to be frustrating as a BP owner to see a serious wobble. The Spiders do often times outgrow a severe wobble like that. My male spider does not have a serious wobble, but as he has gotten bigger, he shows a substantial head tilt. I am thankful thats all it is for him. My Bee shows no vissible signs of any wobble or head tilt though. The wobble can be expressed at varying degrees, so I'm sure she has something, it just isn't noticeable. Hope your reduced spider outgrows the severe wobble!
