not to be critical-but 3 teamers arent the way to go. not enough pay off for the chance of hitting. just my opinion. i'll never say one method or style of betting is better than another but the best advice i ever got is that betting sports is a marathon not a sprint.
if you hit that parlay I will be very surprised. Rarely in bases do three big favorites cover. If it was that easy everyone would do it. Good luck, but I agree with these guys when they say this is a marathon.
