Dominic Dale has his complaints about PTC.
No money, no audience, few points, high travel expenses, excessive disruption of personal life.
Suggests cutting the number in half and doubling the ranking points.
The prize money would double for each installment, and players would have more incentive to participate.
Ding, for example, ignores PTC. (I see he is playing in PTC 10 starting Monday)
And by putting all the tournaments on the continent, PTC would serve to promote the game.
