Meaningful PT stats for NL/PL tournaments

[rabbitlover]

New to using PT; playing mainly tournaments, and would like for users of PT to give me a rundown of what they consider to be the important stats to follow; both for opponents and monitoring my own play.

I am particularly interested in what stats should be used with something like PokerAce or PlayerView, loading real-time stats onto a cluttered piece of desktop real estate.

It would seem to me that in NL tournaments some info like "total aggression" is going to be a skewed number that won't mean much.

All thoughts appreciated.
