i dont think the wobble can be bred out. dominant morphs are typically the most outbred and outcrossed morphs, people combine it with anything and everything and have no motivation to do any inbreeding with this morph.
i think its just the gene, one gene that causes both: spider wobble and spider optics. if it would be two genes that are very close together, i think by now with the tens of thousands of spders produced, someone would already have lucked out and seperated the genes via a random chromosomal crossover.
champagne also has the wobble with quite a high consistency.
