Like others have stated all spider and spider morphs have it to an extent. With some of my spider combos I only notice it when the snake is feeding. For others it can be noticed all the time. It comes down to the individual snake in question as to the extent that the wobble will be displayed. But even with the wobble, all my spiders and spider combos eat great and those of size have bred well regardless. So don't let it discourage you from working with this great morph.
