If Party is too tight for you, I'm guessing you must be playing at Paradise. Not many other looser options.

Yes, playing at the loosest site in the world can conceivably net you 6BB/hr, but don't be surprised if it swings back the other way, either - with looseness comes variance. I ran amazingly great for my first few weeks at limit before what I call The Big Plummet™. Now I'm over 5BB/hr in my first 3000 hands at 1/2 6-max (and that's mostly at Stars) but I harbor no illusion that I'm really that good.

Advice: keep learning.
