I've used all 3 poker trackers (HEM, POkerOffice, Poker Tracker 3) but I like HEM ( Holdem Manager) the the most.
The site I play at, my HUD will show the stats of the players at the tables I open up. Within 10 minutes, my HUD will show who the fish are. The tables with fish, I will join the waiting list. The other tables I discard and open up new tables to find more fish. I also keep a list of names of bad players that I look through the tables to see if I can find them. I usually can get 5-6 good tables after 20 minutes. When a table goes bad I open up some more to find a replacement.
