Yea, Im not all that great at table selection, recently I just add my name to about 10 tables with high pot averages and sit at the first 8 that come up. Table avg gives you a very general ideas of tables that are good to play at, but you do have to sit at them for a bit to figure out if they have a good balance to them. So usually I just play those tables and then swap out any that I feel are still too tight.

Again, nothing too scientific, just some basic things I usually do.
