This episode of Tennis Channel Academy was great:
http://www.thetennischannel.com/programs/EpisodeDetail.aspx?id=3749
Henin actually talks about how she hits her backhands, topspin and slice. She even says that she uses her wrist for the one handed topspin backhand ("at the end", in her words), and you can see it in her swing (in the show). I think you need to subscribe to TC in order to see it - I couldn't find it on youtube.
Hey, I'm just the messenger and I have a two handed topspin backhand, so don't shoot me!
