A word of advice for the micro limits, overbet everything.
PF raises of 10BB, flop bets that are bigger than the pot (on this flop I'm raising to $0.50 and then shutting down if anyone calls.) It sucks cause you wind up building big pots and then getting sucked out on but you need to make them pay through the nose for those times that they don't hit their 2/3/4 outer.
