As far as I know, breeding a spider to another morph/normal has no higher a risk of deformity (like kinks) than other mutations out there. I'd expect wobbles in any spider/ spider morph combo, the variance of severity for each individual can be quite random (minor wobbler throws severe wobbling babies, vice versa)
Spider to spider breedings are seldom done. As far as supers are concerned, no one has proven that there can be a homozygous spider, it is believed that it is a lethal gene. As far as we know none have ever been hatched.
And I was beaten to it... lol
