Table VP$IP doesn't tell the whole story. I see many 3-6 players appearing as TAG who play weak postflop. (Fish in wolves' clothing).

While a table VP$IP of 25 or more almost always indicates a good game, it is not a requirement. A table with average VP$IP of 20 can have 1 or 2 really loose and bad players while the rest are tight, but usually some of tighties don't play too well. Such a game can be very profitable.

You need to hold your own against the good players while exploiting the weaknesses of the bad ones. It's not all that hard to do, especially when you use PokerTracker + PA Hud to keep track of your opponents' styles.
