I'm wondering if it's like Perot politics where we are splitting the GOP vote by having them run against each other. Players who have one of them at #1 wouldn't also play at the other but they would if they didnt have the first account.
The downside is Bookmaker and dsi don't get credit as their own brand but they'll rank higher if they place top 5. Also, your 6th voted top book will make the top 5. What do you think?
