I was at MGM a couple weeks ago on a Thursday night. Plenty of games running, but there was very little money on the table at the 1/3 games. I scouted other tables after I sat and half the table had <$100 and only one person had over $300, but they were all the same. Higher limits seemed to have much better action.
The 1/3 PLO had a ton of regs but there was plenty of action. The few dealers I chatted with seemed to agree the PLO was generally soft.
