I do lucky 15’s on horses. but only if prices are ok. Unless you doing draws/outsiders lucky 15’s/31’s etc are not worth it on football bets Or for that matter very short priced horses. You could have 3 winners and not get your money back, which seems a bit pointless. If I want to try and ‘cover’ myself, much better to do, say, from 5 selections, do 5 fourfolds and an acca. But generally with football its all or nothing!!
