Are you seriously getting into breeding because with that kind of logic and statement it's gonna be hard for anyone to take you seriously
People are aware of wobble is not a secret and if they are not all I can say is that before purchasing an animal (any animal) you do some research prior to acquiring the said animal.
If there are morphs that make YOU uncomfortable and that you do not wish to work with, than it’s simple don’t buy them, and don’t breed them.
Spiders are not for everyone just like some other morphs are not for everyone either.
There is a morph that I chose not to work due to issues as well however the difference is that unlike you I do not look down on people who chose to do so that specific morph is just not for me.
The bottom line as a buyer or future breeder (no idea what your level is) is to be knowledgeable about what you plan on buying and/or breeding and decide if that animal is right for YOU.
