Do you avoid morphs with known genetic flaws?

Stinkpot turtles, green anoles, rosy boas, and many species of tortoises don't even have morphs. People still breed those.

Of COURSE there are morphs of these species...and if there are any tortoise species in which morphs have not yet been discovered, the moment random mutation blesses someone, it WILL be propagated. Species with no morphs still being bred? Of course...because there are no morphs. The moment one shows up, people will breed it.
Even if there are no morphs, people aren't going to leave things be...they will selectively breed for the traits they want, instead, changing the animal's appearance more slowly, over time.

As for worse problems than spiders...such as what?
Increasing the ataxia beyond what you see in spiders produces a non-viable animal that can't feed well, and doesn't thrive. So there is nothing worse...worse doesn't work.
