At the end of the day, the pro players should all understand that for their pay to grow, their fan base must grow. IMO, the best way to do that is to completely ban all slow play, and make a concerted effort for all pros to play FAST! It's such low hanging fruit, that is completely possible by the players today. Does not need sponsor money, in other words, to make it happen.
The modern players of Earl, Schmidt, Filler, Shaw, etc, are super fun to watch.
The same (roughly) speed players of Souquet, Kaci, Ouchan, CW, Bassivich, even Alex P sometimes, are brutal to watch.
Shane and Efren speed should be about the slowest allowed on tour. I'm not saying these two are slow, I'm saying these two should be the baseline.
