I got Charlie's message so I came back just for this!!! Ok, maybe not
Damn Jersey I am at this moment like shouting from you staying near the Meadowlands for a little vacation.
Thing about picking solid books is there aren't any without a doubt. As it is all we can do is act on hearsay because I personally know the owners of two books and I wouldn't include them in this list for reasons of independence. So here goes:
1. Pinnacle - just because I believe in their business model.
2. Canbet - just the way they operate makes me believe that they are the closest thing to an old-time book, one that moves on action and not air.
3. CRIS - everyone says so, so why argue? I heard they are about as funded as you can get.
4. WWTS - similar to CRIS argument
5. NASA - not that I would say they are a good choice to play with, especially if you might even beat them, but if you are just asking safety hard to argue they don't have a ton of money
6. Olympic - call it a mix of a CRIS-like reputation and a bit of Canbet style theory. Like NASA unless you really see a lot of props you want to play, not the best choice for a player but certainly safe.
7. WSEX - solid shop that could almost thumb their noses at the law, they seem to picked up a lot more positive effect than negative from the Jay Cohen ordeal. I am trying to remember the fool that wrote "get your money out, they are connected to a convicted felon and the wall will come down on them soon" about a year ago. Maybe someone can refresh my memory.
Note that a lot of these books I don't keep an account with. To me it makes little sense to keep a book with regular or high vig unless they have lines that differ from the rest.
