Thanks for the info, I'll take a look. I was using Super Sculpey for some models, but sometimes it becomes too soft, it's hard to keep the good shapes.
I have not used Super Sculpey yet, so I can not compare them. But for Premo, a good skeleton is always necessary, so that the clay layer is not too large. Otherwise, when baking everything will hang, for the rough layer you can use some sort of self-hardening material.
