I wouldn't say that there's a morph that I specifically dislike. I dislike muddy looking snakes. That could be indistinct markings - or it could be too many markings. Honestly, even though both Balls that I have are marked, the fewer the markings and the cleaner the colors the more I like them, generally. I suppose one that I don't care for is Champagne. They just look too muddy and gritty to me.
