The Harrington books are for tournaments...not cash game. Why not make up your own strategy based entirely on table conditions. There is no one-size-fits-all strategy for NL that will give a max win-rate. That's not true for limit either, but it is exponentially based on table conditions for NL. Once a book is published, alternative strategies will become more profitable. BTW, Super System is good as long as you're not playing against total donks (which is a lot of the time in games that are less than high limit).
