SS2 Add on or New Edition of SS1?

Is it necessary to buy both, or is SS2 enough?

besides Doyle's NL section, the contents of SS1 and SS2 are almost completely different in terms of what game types they cover.

SS2 covers more of the "newer" game types that are popular with high-limit pros nowadays, like O8, Stud8, PLO, Triple Draw.

SS1 covers more of the classics like regular Draw, 7-Stud high, and lowball.
