A spider or bee with a visable wobble or corkscrew can produce those without a visable wobble or with a visable wobble. On the other hand you can have one that you don't notice do it.....and they can produce big wobblers. Just part of the morph! The breeders that deal with these morphs will tell you.....even though you might not see it all the time...it is always there even just a little.
