Westys, not sure what youre looking for but simply backing the favourite or even pre-post favourite will give you about 30% winners (or about 1 in 3 ) if you want better odds just take the first horse in the pre-post betting forcast quoted at 5-1 or better this will give you about 15% winners. Of course in both cases it will result in a level satkes loss, so your staking plan will need to be something special!!
