G'day William,

I'm sorry but Shaun is correct!
Investing $336 each race will send you to the poor house very quickly.
However, utilising the NSW Tab flexibet you can still back that many of starters each race and only invest $20 or so.
If the plan is any good you should be able to build a sizeable bank fairly quickly and increase the investment amount,
eg box 8 starters = $336
invest $20 on the flexi-bet and you will receive 5.95% of the winning dividend if you are successful. It doesn't sound very much but it protects capital and it is a much better approach than potentially losing $336 per race. Betting exotics with that many starters, you would be unpleasantly surprised at the number of divs which don't even recoup your outlay.
It's food for thought so I welcome any opinions.

Cheers.
