Honestly, if i had a problem with the wobbling, i wouldnt work with spiders or their combos and i know there are some breeders who probably dont. Just like some people wont work with caramels because of the kinking. (I'm waiting for the Ultramel project to get bigger, I dont really want to work with caramels, for example). But i DO have a spider and i DO plan to breed her. Its a choice just like everything else in the hobby.
I think we should start a poll to see if other peoples spider and spider crosses exhibit the wobbling/tilty/whatever problem. But i just love polls. lol
