Some spiders actually may never show their neurological issue their entire lives unless under great distress such as having an RI or even being stressed from whatever reason. My spider hasn't ever wobbled, though that doesn't mean he won't as an adult. It can vary between each snake, but the neurological issue isn't too bad.

Like the first post, the pinstripe gene has completely nothing to do with the spider gene. Pins are awesome morphs though, definitely want one of those.
