Win Parlays vs Pick N As someone who plays primarily horizontal bets, I spent a fair amount of time considering these options. In the end, for me, the horizontal wagers proved to be the right way to wager. Here are the primary factors:
1) The takeout is reduced for horizontal wagers.
2) There were more inefficiencies in the P3-4-5 pools than the win pools.
3) M/L choices (after the first leg of P3,4,5) were slightly overused.
4) I seldom found myself looking to change wagers after submitting my initial tickets.
My conclusions resulted from research conducted around 2010-2013. I have honestly not conducted any research since that time, But I have not encountered any reasons to make a change.
