For low limits, NL $20 and NL $50.
The tables are pretty empty for the most part. Seems that most people are nut-peddling and shortstacked at these levels also, or doing both. I can't believe how many people I've see playing the double up and leave style or the pushing allin w/ QQ or higher method. The tables do have some decent VPIP's sometimes, but usually you can clear the field with a raise of 5x or more...sadly, most of the time that clears the whole field.
People are playing PP's for raises from 77 up in some situations, but I'd say 90% of raisers won't push the flop at all unless they hit it pretty hard. The software is ok, but I would like more ways to seperate certain games from others maybe an extra filter or something.
The bonus is pretty hard to get if all you play are low limit games, but for NL $100 or NL $200 they should be a piece of cake. Like I said though, with all the nut-pedaling going on and the lack of game selection, it's tough going for us small stake players.
Just my 2 cents.
