Personally, I have deposited on only bol and full flush
, and don't plan to again. I just don't like the 2 sites very much. They're very small, meaning not a large volume of players, and they have very small gtd tournaments compared to ACR/BCP/Winning Poker Network. That can be advantageous to some, as you typically find yourself playing against the same bunch of people, but for me it took to much to make a substantial profit, as a grinder. If playing for fun here and there and aren't worried about how quickly you build up, then bol and full flush could be fine.
I've never withdrawn from any of these sites, so can't speak on that. ACR is the only site of the 3 that's really made a name for itself as of late, they have a lot of players, a pretty solid daily tourney schedule, and from what I hear, cashouts are fine. So that's where I would recommend based on what I've read around here.
