PokerOffice (or Poker Tracker): What's your favourite overlay stats?

Hey!

Hi! I'm quite new to poker and poker online tools especially.
I'd appreciate your thoughs about PokerOffice/PokerTracker usage.

If you use PokerOffice or PokerTracker... What's your usual overlay stats for cash tables or SnG tournaments?

I currently have:

Vol. $ Put into Pot
Pre Flop Raise %
Nr Of Hands Session

Aggr. Factor Flop
Aggr. Factor Total (PF)
F-T %
T-R %


Vol. $ Put into Pot shows naturally how lose/tight a player is. I think it's a better choice than Saw Flop% or Saw Flop Not Blind% since it's a volunatry action reflecting the tendency of the player..

Then I look at the following stats to measure a player's agression:
Pre Flop Raise % - This stat tells me how serious I should treat a pre flop raise of a player... If he has over 15% I will re-reaise with any pair and AK,AQs-ATs
At what percentage you think you would re-raise with which hands?

Aggr. Factor Flop
Aggr. Factor Total (PF)

I don't really know how to understand the aggression factor stats. I know that Aggr. Factor = Bet% + Raise% / Call% , but sometimes a call might be also quite agressive. Usually if someone has a higher than normal agression factor I tend to call with more hands and try to slowplay for a check-raise from time to time.

F-T % and T-R % :
The flop-turn and turn-river stats might indicate if you should push your good hands somewhat stronger or softer to extract most value?
