OK man, I have the perfect bonuses for you. Go to
www.casino.net, they have a cool deal where if you play 500 raked hands, you get $100 free. The beauty is, its clearable playing .10/.20, which seems to be perfect for your BR at the moment. The games are incredibly soft, as a casino site might suggest, and nicely passive too. The only problem is, the bonus only counts on hands that you enter the pot in, but still, grind it out and you could come out hugely ahead. Also, there is a whole network of these sites, with similar bonuses, which could easily get you up to the right BR for .5/1 again. Check out the thread in the internet bonus forum for more info.
