Oh what a wonderful crew :)...although I have to admit I'm biased.
I have to agree with you about the Resinsouls (or their cousins Bobobie) that while their posing is a bit squirrely they have surprisingly lovely facial sculpts ~ and as you said, excellent for first mod projects. I'm really new to this and my poor Su (Bobobie Ariel) was my first time re-stringing and doing a full face-up etc....the poor thing being a complete guineapig ,but it wasn't as daunting as taking part something in a higher snack bracket.
*pets little fire element*
I just did a quick count of my herd (here or on order) and just realized that Resinsouls are like potato chips ...apparently you can't have just one. >D
