I apologize for responding days later but didn't want my response to be about the WO Mile contenders but rather the format of the ticket you describe.

If a horse is an A I can't have a ticket where that selection is off the board. The entrant is an A for a reason, because I think it has a high percentage of winning or his odds are drastically over inflated. I don't want my A horses to run 1/2 and be light because I spread and played them to finish behind B & C horses.
