Grinding question.

I've been playing for about a month now, deposited 100$ on Party and had my BR grow to 400$ playing 0.5/1. Then unfortunately I had to withdraw most of it because of real-life bad beats and had 100$ left. And now after a bad run I've got 70$ left, which is too little, especially because I like to two-table mostly. So now I'm going to move to a lower limit, probably 0.25/0.5. But the question is, where should I head to? A nice bonus that's feasibly clearable at that limit wouldn't hurt.
