As already hinted at elsewhere, when we are looking for other-than-live-market bets we do need, in most cases, to compromise on price.
This pattern tends to be the case with the nonlive- market betting systems I have come across. The latest of these is the SHARP END SYSTEM from Bernard Hibbert.
I was immediately concerned when I saw that Sportsworld Publishing were selling this system. (Yes, their superb Cashbooster system has really been a cashbooster for them! If it actually selects a qualifying horse before the 2012 Olympics I will throw a party!)
