i agree with the previous poster.
the success of most books and systems in the application applied by the punter.
you have to be committeed and dedicated to really make them work.
i have bought a lot of books and have settled on my own system due to the time constraints and amount of fun gained from the hobby.
i realise i cant teach anyone else anything but i enjoy the successes of the forum and fellow punters.
good luck with the book but its a difficult game
