It is in theory that all Spiders have, or are highly susceptible to "The Wobbles".
But it has not been proven that breeding one results in more "wobblers", in fact, most experiments I've seen have around the same ratio of "wobblers" as regular Spiders... but then again this is all in theory and there is no validation to it yet, so it will be a risk. It just depends if you are willing to take that risk.
