Hi Tim Prefer Vicky...because I want to experiment the partial muscle/Vicky and I have a lot more Vicky maps/faces etc. The Michael map has been a help at school, being able to pose a figure in various positions, and seeing the anatomy on the arm, leg, etc, is a big help. There are more Vickys than Stephenies out there, I think Vicky would give you more sales. I know Stephenie is supposed to be more versatle, but she doesn't have a large a selection of products, and I just like Vicky's look(no offense Stephenie lovers). Sorry that I have a long wait, but good luck on your projects.
