From what I can tell.... this is still a very hotly debated topic... LOL. I personally believe all spiders have the wobble. I agree with TessadasExotics on the statement of wobble isn't just the corkscrewing... but head tilting as well. My Spinner Blast from NERD has a slight head tilt... and I've been to NERD and seen his 4-5 gene snakes have the tilt or wobbles from having spider in them... which right there proves that the wobble never really goes away... just wanted to see what others have heard, or had experience with.
