Well the book I mainly use is Pinnacle, best prices and widest variety of games.
I also have a good mix of dogs/faves, throw in a few draws, and split between asian and 3-way handicaps.
Matahari, don't know percentage, I would have to analyze my plays, but I know I very rarely take big faves, and am not afraid to take long live dogs, so it has to be pretty good.
