Whats the 2nd most popular game after Hold em?

[Mr. Sakuraba]

Ive played NLHE for a while now. Im looking for something different, but not something obscure.I like razz but ive never seen it spread live, and only at ftp online. I go to the casino's in mississippi all the time and would like to play something besides nlhe. Limit he is by far the most popular game there, but I'm looking for something non-holdem based.

Ive recently tried plo and like the game. But is that my best choice? Is stud still very popular? low ball?
I want to go into a room and not feel like i have to play HE, or wait 4 hours for an obscure game to start. Opinions?
