The general consensus over these past two days is that it's been the PLO levels that have played the fasted, and that's understandable as players, a lot of the time, wanted to see a flop at least. The game generates action. Period.
The one level exception to this has been the second level of each match, the first PLO level. As they're still fairly deep it's easy to get to see a flop cheap. Beyond that point the players seem unwilling to get too deep into pots. Because of that we've seen virtually no showdowns this level.
The next time PLO comes around, that will all have changed.
