I have 8 books that I use, including 4 locals who have websites. If you bet futures/props and/or golf (I play A LOT of futures and props for all sports) you have to have multiple books because the odds discrepancy are sometimes drastic. I bet most of todays futures at betonline. I actually got a bad line on Stricker if you have an account at Bovada (another one I use) and plan to tail, he's +1600 now... Other's include 5dimes and Pinny. About 90% sure one of my locals takes all lines from bookmaker. Not sure on others...
