When I played there, I only cleared about $200-$250 per month playing 10k hands at NL50. With the change in bonus structure about 6 months ago, I found that playing NL100 was only slightly more productive. I've still got about $400 in bonus there, don't think I'll go back as I'll be losing money not playing more profitable bonii elsewhere.
Plus, it's a rockfest so your bb/100 may suffer as well.
