In my opinion, California Sports is damn good, but strongest in CBB. Master Sports is going throug a dry spell at the moment, but if you check out the Oklahoma Sports Monitor, you'll see that he is one of the best in NBA selections. The one thing I do on a regular basis, is to refrain from playing any unders from any service if the line is < 8.5. Anyway, that's MY opinion... and Master Sports may be rounding back into form... he nailed both 4*'s yesterday and I played both on the spread as well as moneyline... doing the same today with the 76ers selection.
Good luck in whatever you do!
