Even if Shaw and Morra have accurately represented the feeling of the players regarding the equipment, what matters is the marketability of the game, which rarely, if ever, coincides with what the players want.
What the fans want and what the players want is almost never the same, but Matchroom needs to be on top of the opinions of both in making a decision that serves the best interest of making the game entertaining so it can be marketed.
My opinion is that 9ball is less entertaining on 4" pockets than it is on 4 1/4" pockets. As we've seen, the current format makes the break almost trivial. Per AtLarge stats, at the recently completed world championships, the break and run rate was just 19% (same as at the World 10-ball) and breaker won the game 56%. Those stats are on the stream table, where the best players get most of the air-time. We've also seen somewhat more conservative play in stretches, with players taking conservative position routes and passing on some tougher shots.
Yes, we've, more or less, turned 9ball into 10ball, but is that what we want?
