I plan on having about 10K to wager, American player. I really only want to use one book, maybe two. I have accounts open at Bookmaker, Heritage, and 5Dimes (took free play over reduced at 5Dimes like a moron). Anyway I'm leaning toward bookmaker mainly because of "financial security". I mainly bet NFL, pretty straightforward, not many parlays, teasers, etc. Which would you go with, if you only wanted one?
