8-tabling, good tables?

[xCEO]

I'm currently 4-tabling at 3/6 party. I live in Europe and I usually play around 4 a.m US time. At that time it's not very busy on party. At 3/6, the Fish from the US are sleeping and the Fish from Europe are on their normal daytime job. To find 4 good tables I use poker-edge (great program!) and playerview. It takes some time, but I usualy get pretty good tables after some time.

A few days ago I began adding some tables. Which leads me to my question. How do you 8+ tablers find good tables. And are their enough good tables? What is good enough? (av. VP$IP?) While 8-tabling, do you often close tables and open new ones?
