A question for those with a good knowledge of SSHE

I've heard so many endorsements for SSHE. Even though it is a limit book I am wondering if reading it will have a positive effect on my game even though my current focus is on no limit hold'em cash games and tournaments (live an internet)? Is there enough theoretical content that would apply to both forms of hold'em or is SSHE more about technical applications in limit only? I will read it sooner or later but I'm concentrating on learning NL right now before I go back to the limit tables. I value your opinions.....
