Does it appear that bowler interest in the PWBA is starting to wane?
In 2015, the first year, there was talk of capacity fields at each event. And the numbers appeared to be equally as strong, if not stronger, in 2016. But the field sizes are arguably lower in 2017.
Essentially, given the cash ratio is somewhere in the 2:1 range at most events, I don't see how those numbers justify any long-term viability and success. Eventually, the sponsors that the PWBA does have will demand a better return on investment.
