Nathan Apsinall at 5.8 exchange, or 5.5 with some books to win the World Grand Prix is a great bet imho. Been playing the best darts of any player this week. Averaged 105 in the double start format last night. For those unfamiliar with it, it means you have to hit a double before you start scoring.
Most of the players reckon it takes 10 points off your average. 105 is a brilliant average in regular darts, in double start it is outrageous.
