I don't know if you made the price to high or not, if you did it's not by much. I just think that there would be a lot of chances each game to win taking 5/1. There would be games that laying 5/1 you would think that you should win and late in the game someone makes a three railer
I just feel that you can make a multi rail bank on average more than once in 6 games. If you make one once every 6 games you break even getting 5/1.
The other props about solids and stripes are OK providing the balls are racked randomly. But then a slight adjustment must be made for the solids because there is 8 solids and 7 stripes.
But I still like Arties suggestion on if you can lay 5/1 on the player winning the last game that he'll win the set.
