Actually live I'm comfortably ahead at 10/20 and just last night sat 20/40 to the tune of about +10BB over 4 hrs. As several OP said, it's fun.

My experience (mostly at the Hollywood Casino in Aurora IL and Parkers in Seattle) is that mid-limit live plays like small stakes online. In fact, at the Hollywood, the evening 10/20 game is _softer_ than PP 2/4 daytime. The drunks all like to gambool and jam. Just gotta play good cards, make em pay, standard operating procedure.
