Exactly - and like I said earlier in this thread - the degree of wobble is as random as the degree of white on a pied.
You can have a low white pied throw high white pieds, and vice versa.
Same with spiders. You can have minimalist wobblers throw train wrecks and train wrecks throw spiders with barely detectable wobbles.
If the wobble could have been selectively bred out of the spider and all spider combos, it would have been done already.
