Table Selection help...

[chitown]

I was hoping to get some help with table selection, I have browsed the low limit board and couldn't find exactly what I am looking for.

I guess a little about me, I have been pretty successful playing part 2/4 over the past several months and have recently started using PokerTracker and game time seriously to try to improve (and eventually bump up). I only play 1-2 tables.

I hear table selection discussed a lot and was hoping someone could describe the best way to use these two tools to choose a table? I know you observe a handful of tables, but I'm not sure where to go from there -- gametime doesn't show stats until you play right???

Also what levels/types of table are you looking for? What are the most profitable -- vpip, prflop raise, etc?

I am a tight to semi-loose aggr/aggr player (vpip has been between 19-21)

Thanks!
