I know for the Chines events it's not financially feasible to take even 64 to China. From the Guaranteed £3k you get from winning a qualifier you have to pay flights and food and hotel. (Hotel is paid until the day you are beaten so if you have booked a flight for later in week you are liable for hotel bill. Take 32 to China with the £7k guarantee and its more feasible.
And put on an Asian swing sort of thing. 2, maybe 3 events back to back, would save hugely on flights.
