I think Voss' allure is more due to the fact that he has a big fan following. I disagree with just about everything he has to say regarding ball tech but you can't deny that he has a big groupie club. Maybe it's the Hasselhoff-like hair. (g)
The international thing, IMO, was probably conceived back before Belmonte made himself exempt, and then they just decided to go ahead and run with it.
If it works, it could increase the PBA's audience worldwide, similar to the way the PGA draws golfers from all across the globe. Perhaps that will increase international sponsor interest which will in turn increase the prize fund. This is reverse-engineering at work, but hey, what other choices do they have?
