This has been tried in what was called the "Accu-stats Game Show" and it was quite enjoyable, but it was a novelty. To play this way on occasion would be OK by me, but this should never become the standard rule set.
The monumental struggles we just saw at the Mosconi should quiet the "nine ball is too easy crowd" around here for a while. Per At Large, Team USA won just 46% of the racks in which it broke. That means that if they'd been spotted the break by Europe for the entire Mosconi Cup, they still probably would have lost. Of course, part of that is due to the fact that tough equipment was used, but elite players SHOULD be competing on tough equipment with neutral rackers.
For both nine ball and ten ball, the thing that can make it too easy is "rack your own." Remove the rack mechanic issue and the pattern racking issue from these games and they are both excellent games. With rack your own and pattern racking, as Chris Melling has observed, both games are a little broken. Without them, these are great games and winner breaks could be used in all major competitions.
