If you're thinking of adding hands to your preflop strategy, it's hard to get anything useful from your hand histories. If your changing the way you play them, it's probably best to just make the change and test it out. What reviews really help with is post flop strategies. Mess with the filters, check out all of your 3bet hands, check out how you play AQ and AJ after the flop, check out how you play against different types of players.

I haven't been in there in a long time, but FTR used to have a ventrilo server. We may still have one. The info should be in a sticky in the commune. If not IRC works just as well. PM an ftr'r that plays at your limits and ask if you can sweat each other a bit.
