Do any Online Pro's NOT use PT?

[mattw]

Most players, especially pro's, semi pro's, etc., recognize the value of PT. Even casual players use it extensively. For long time players, does the info contained in PT become intuitive? One knows how many flops are seen, preflop aggression, etc.

Can one argue for not using it? Other than for analizing one's own play(simple paper bookkeeping will get the same results), does the info on opponents justify the use of it? Granted PT and add-ons helps to identify oppenent's tendencies but relying on the info could be misleading. Perhaps a husband/wife, boyfriend/girlfreind, college room mates use the same account and play differently. Perhaps the opponent is an alcoholic/stoner/crack head who plays differntly according to the stage of the binge he/she is in. I guess what I am suggesting is that careful observation of the opponent during this session is more important than any prior info that may or may not be related to past experience. Does note taking and tagging of the opponent result in the same info that PT would provide but with a more realistic veiw?

If poker is a people game, does relying on a stat program diminsh the EV because someone is playing 12 tables using PT to make decisions for them instead of playing 4-8 tables and using current observations to make decisions?

Please discuss.
