actually, in my town, it's much harder to find a limit cash game than a NL game (cash or tourney) nowadays. which is why i'm starting to get into NL.
i absolutely agree that playing other variants of poker will hone skills useful to your personal game of choice. let's not forget good old 7 card stud! i started as a stud player and found it unbelievably easy to read the board when i switched to hold em. because in stud you have to read 4-5 at the same time.
