I look for loose tables more than passive tables. If I'm at a table for an hour and the average V$PIP is >30%, then I'm a lucky man. If the average V$PIP < 20%, I should probably move tables.

As for passive or aggressive, if the table is loose, then it's nice to have it be aggressive preflop with a >7% average preflop raise at the table. I can then sit, wait, and expect some action when I come in for a raise with good starting hands and/or good position.

Post flop aggression close to 1.0 would be passive. But that number is less important than observing how many continuation bets get called. A lot of tables end up with one or two policemen who call continuation bets with a TPWK hand like Axs where all they got on the flop was a weak pair of Aces. Some of those guys even call a turn bet just to see if you're bluffing in late position with garbage (which sometimes I like to do). THESE guys are a bit of a pain because you need to show down a real hand. So, after they snap off a continuation bet or two, you just have to wait for a real hand like TPTK AK, or an over pair, then bet the flop, the turn and value bet the river and get paid of by their AQ or JK TPWK hand. Of course, they hit pay dirt once in a while, but they often telegraph that by betting a big hand instead of calling like they do with the weaker ones. These guys are pretty rare, however, on-line. Most will fold marginal hands to a decent continuation bet if they miss the flop and you have position on them.
