unless you can really dominate loose games through actual play (BB/100), there's not much to gain in pokerroom bonus in terms of ratio of rake paid to bonus paid back:

minimum revenue per player/point - 10 cents
1 point bonus pays - 14 cents
maximum rakeback value - 140%

Party (7x)

with Party, Intertops and Absolute on the horizon this weekend, I'm apt to skip pokerroom this time around.
