I felt the same when I first got into ball pythons. Spiders and womas are very different though, as far as I know wobbles is only associated with spiders and their combos, so woma should be wobble free. Also spiders have white sides very similar to a calico and their pattern markings tend to thinner and more spider web like then the woma, which is more of an extremely reduced pattern IMO. Another noticable trait of the spider is that they have very defined head markings.
