I like poker tracker. As you mentioned, I too am not a in game HUD user. But I do like to be able to review after games and poker tracker will save all your
hands. Once you've 100k hands or so, you can with less - more is better. The data is really helpful.
I'm still new to figuring out the ins and outs... and I'm sure there's other good stuff out there too. But Poker Tracker has free 30 trial. When I put it on my system, there were actually 10s of thousands of hands it pulled from pre-install- that were on my HDD,somewhere. lol.
