I don't find the bodysuits very useful, but people who are doing comic book superhero type renders might have a different view. :-)

Agree about David. I find his body and face morphs a lot better than M2 or M3. And I really like his "look" a lot better than AM, which somehow looks too "smooth" for my taste (even the morphed versions I've seen).

David looks like a slender young man, but don't be fooled. He bulks up and "ages up" better than M3. He's short, but scaling him up to about 115% fixes that.
