If you want a list of morphs to avoid because of potential genetic problems, the website linked earlier has a list. It helped me generate my own list of snakes to avoid working with:

Spider, Champagne, Sable, Hidden Gene Woma, Desert, Caramel, Spotnose

A few of them, like Spider, HGW, and Caramel Albino I had already known about, the rest were news to me. Mind that I don't really see the bug/small eyes or the duck bill as big enough problems to avoid those lines (Black Pastels and Lessers are some of my favorite lines), but the lethal genes and wobble are on my avoid list.

There does seem to be a problem in this topic, since the beginning, of one group and another group being unable to form and maintain their love/dislike of the spider gene without feeling personally attacked by the other group. Part of this is likely due to the fervor in which each group holds their views, and part of it is likely due to internet misunderstandings.
