After finding out his.. "shocking news" I got to where I don't much care for him, but that's not the point of this post. You did a great job on him *may just have to download shortly* (net wants to act up right now)
as for Simming him, I know the feeling I've been trying to Sim my fave nsyncer (Chris) and I have YET to be able to make one I'm happy with, he's a tricky sucker lol.
