hi, i am new here and making my first post.
i have recently purchased super system 2, but i have been told from various sources that it does not replace supersystem1 and and been even recommended by some to purchase volume1.

i have also been told that large sections of volume 2 are simply reprints from volume 1.

is volume 2 a complete book on it's own??
and is it worth purchasing volume 1??

i wish to specialise in no limit hold em.
thanks.
