I lost track but it could have been Pinnacle for me also. I always hear stories about how everyone loses the most at Pinnacle despite the reduced vig. But you have to have discipline.
Pinnacle's odds are good to use when you want to bet a game and they have a better line than other books. But the trap you cannot fall into is betting a game you would not normally bet because of their odds. In other words, don't let Pinnacle's odds make you bet instead of not betting at all. That's how it's worked well for me.
