It makes it so much worse, when you don't even know what books they use, how much action they take and how sharp they are. Could be betrussia.com. Don't like this secrecy for a product they advertise as premium. Sportsinsights books for public percentages are square, but at least they are willing to tell us who they are. Its a wide enough range to be accurate. I also like that you can track the public % with the line moves at the same time. All that being said. SO and SI percentages are often very similar and if you are serious about +EV bets, then you need one of these two at the least. If you don't care about the public, then go with SO. Their interface across all sports for the line movement is much easier to use.
