Late mail, do you honestly think that the TAB(s) will keep their pecentages to 115 odd percent once, or if, the bookies have all disappeared?????
Have a look at the take in NZ and Singapore, I think it is something in the order of 25-30% for the win bet. Try holding your own giving away that sort of start with no betting alternative.
You should be very very careful what you wish for just in case you get it.
