There are always plenty of loose tables at the micros. If only tight-aggressive players are left at the table, then it will be more profitable for the cash game to simply leave the table, and not continue to play with them, because winrate directly depends on whether there are very loose fish at the table ))
Even if there is no poker tracker, then in some rooms you can look at the table statistics, which show the values of the average pot in the hand and the number of players watching the flop in the hand. It is always better to sit down at the tables with the highest possible this numbers. And also constantly look in the lobby to see if the statistics of the tables you sit at have worsened and if even better tables have appeared.
