Yea, I know what you mean! I was not aware of the wobble/spin issue when I first discovered the spider morph.
If you are curious, you can look up some bad cases on youtube.com! I have steered clear of the spider morph after I got an earfull from a local breeder about them. I haven't owned one, or even seen the wobble in person, but I think I would worry constantly over my snake even knowing that this is normal! You can look into a pinstripe though! They are just barely more expensive in most cases and very pretty!
