G'day Cairns man, I'm not really the right person to reply, as I'm probably not into the same level of investment, well there again not really sure as my Max bet (for the place, is $200) BUT, I have a LOT of bets:

After many years though I have an ongoing fight to have my bets accepted, (I'm now down to Grandkids / and others) and my profit margin is just under 4%.

In short only losers are welcomed???
