I have an albino spider female that has no visible wobble at all. The only thing that is noticeable are missed strikes when eating but she never gives up and has always been a strong eater. Now I have read that the wobble can come and go in varying degrees so she mat do it some day but I have not seen it yet.

Based on my limited experience, it does not make them any more difficult to care for and I would guess it does not affect their desirability much as there still seems to be a good market for spiders and morphs that contain the spider gene.

Just my 2
