i think tournaments like these should stream online on their main site. the more people tune in, talk about the tournament, remember the odd trick shot or upset the more likely it is for people to actually want to see it live.
it will also help give the sponsors more bang for their buck.
OR... change the surface to grass so it isn't just another, also ran, 250 event!
