most profitable online rooms on partypoker

Hi all

I wanted to get advice on where people think the most money is to be made on Party Poker. So do you think it is better to play $30+3 sitngos, the 3/6 holdem tables, or the 34k garaunteed tourny, etc...? I suspect there is some law of diminishing returns in going to the higher buy-ins/limit tables, as general quality of player increases....

Also, how much can you reasonably make at whatever rooms you feel are most profitable?
