Best Poker book to improve ring game skills?

Just wondering if anyone has any recommendations? While last week I did great in tourneys, this week is nothing but bad beats, absolutely horrible in ring games though. I went to the Library picked up a Sklansky book (Tournament strategy for advanced players though), Hellmuths book, and a Sexton book. The Sklansky book probably won't help me much, I read a chapter in Hellmuth's book and he seems too tight with his advice, says there are only 10 hands you should play, which in online ring games will do nothing but lose you money probably. Sexton, don't know if I will read his book, just looks like a schill for the WPT.

anyone?

Hellmuth's top 10 hands are strictly for when you are a beginner. Exercise common sense and add other pocket pairs and suited connectors once you have been playing for awhile. Hellmuth's book is very good for ring games just omit the only 10 hands thing, assuming you are not a beginner. Super System provides good ring game strategy in both NL and Limit H.E.

I hated Helmuth's (too basic) book but loved Super System - Doyle let's you know how and why he plays different hands and what to look out for. It's a great read that taught me heaps.
