I think the main confusion, especially with the pastel morph is that people ask "what line is this pastel?" expecting to get a straight response. But there is really no way to tell for sure what line it is unless you bought it knowing what line it was. When identifying a morph, there is usually a very obvious answer, when identifying lines, not so much.

I do agree that the different lines for each morph are very very different. I prefer the VPI axanthis to the TSK axanthic, but if you ask me to identify what line a particular axanthic is, I couldn't do it.
