Best Seven card stud books?

Can anyone advise please? (I have Seven Card Stud for Advanced Players already)

I'm assuming you have a basic understanding of the game already and don't need 7-stud by Roy West, a great book but somewhat for a beginner or a low-stake player. I'v read all the books and besides 7-stud for advanced players the only other book I found useful was the Super System by Doyle Brunson. Many of the sections in this 605 page book aren't very useful b/c the structure of the games have changed, but the seven stud section is still great since this game hasn't.
