HUD and questions

I play on a Mac, have not found anything for a HUD until recently found Poker Co-Pilot, seems okay. I tried PT3 for Mac but it would never work and the support people kept asking me if I rebooted my computer. "yes" I said, "did you reinstall?" they said "yes" I jovially replied. "Then did you reboot again...?" seriously?

Okay- at any rate was curious if any one else used Poker Co Pilot and if so what their thoughts were.

2ndly- What Vpip and PFR do you personally use to classify someone as a fish, TAG, LAG, Maniac, etc.

3rdly- what other kinds of information do you find to be useful- especially at a smaller sample size (200 or fewer hands) were you may not see much 3betting or especially 4betting.

Thanks!
