Vinnie if you have gambled a lot of games in your life, there must be some games that have landed on stupid numbers and wish you had that extra half a point. What I like to do is try to find numbers like New england +6.5 with the free half and now the line is down to 5.5 at some places. That can give you sometimes a full point advantage even if you are paying the 110 juice compared to less at other places.
only problem with skybook is it takes forever to grade horse races where other books take less than 5 minutes after a race. and they dont payout western union anymore
