I can quite happily do four tables in NL. Although if four tables hit at the same time it gets a little hectic. I had AA, AA, AKs and TJs all at the same time thre days back. Amost dropped the TJ which would have been a shame cos since it ended up stacking someone with a J high straight versus their T high.

Just in case you get the wrong idea I've also watched two sets go down the gurgler at the same time, taking large amounts of cash with them.
