WSEX has low vig and they stick to the same line so you can scalp it if you are patient and the game goes the way you think it will.
Bet365 is VERY beatable if you pick a good spot - they change the line and keep the vig steady, so you can only hope to middle it. You HAVE to pick a side for Bet365 and just look for a better line because the vig is too high (-120) to make any money by middling.
