I like the idea here, Mike, but what matters certainly varies from fan to fan. You can put me with the crowd that cares much more about star power than depth. Field depth matters little to me, as I rarely watch stage one at the WNT majors in the first place, in part because of the lower quality of play, but also because there is no shot clock.
That is why I'm so upset that the bickering between WPA/Predator and Matchroom has made it very rare to have all, or nearly all, the superstars in a single field.
Right now, our game, arguably, features three of the ten greatest 9ball players in history in Filler, Gorst and SVB. It used to be quite common that we saw all three in the same event, but pool politics have made it rare, and the fan is the loser.
Depth of field is nice, but like most other sports fans, pool fans want to see the superstars more than anything and field depth can never be enough to overcome their absence.
PS My guess is that the World 9ball will come out on top in your study.
