How can people keep the game interesting for future generations?
Speaking as a fan, I'd say this is the crux of the matter, and I'm guessing it underscores some of the concerns expressed by the initial poster in this thread.
With respect to the break, we've already made some progress. I think that rack manipulation and pattern racking are starting to go by the wayside in top tournament play. Having neutral rackers makes the rack fair, and more and more, we are getting neutral rackers, at least on the stream table in the late rounds.
We get neutral rackers at the US Open 9-ball, the International 9-ball, the China Open 9-ball, the WPA World 9-ball, the World Cup of Pool, the World Pool Masters, the Mosconi Cup, the Predator Championship League event and in some other big events. The days of rack manipulation in the late rounds of the biggest events are almost behind us.
Nine ball and ten ball share the same problem at top pro level - the runouts are too easy. That's because the equipment hasn't been toughened to keep pace with the ever-increasing skills of the pro community. Personally, I don't care how easy or tough the break is as long as the runouts are as tough as befits the top players.
Once upon a time, pro pool was contested on 4 3/4" and even 5" pockets, and pool organizations came to understand that this did not represent a sufficient test of the skills of the elite, so 4 1/2" became the norm at pro level. I think we've come full circle and it's time to tighten things up once again.
