Gday Testa,
i reckon if ya showin a profit at flat stakes, i think betting set % of your bank is probably as good a way as any to go. I Just look for the overlays on my prices, of the horses I rate as single figure odds and bet that way... seems to work ok..some days good some days not so good... Good luck with it.. ya can certainly sniff the chances out
