Please let's not get back to this question, winner's vs alternate. Both formats have advantages and disadvantages. IMO alternate is better (look at tennis), but again, both are okay. Just run enough tournaments in both, so that everyone is happy. There is no black and white in this matter.What?!? First of all we need to lose the whole “format” thing. In 9 ball the winner breaks. Lastly, the point of winner breaks is you can be down 10-0, win a game and get the break, control the table to get back into the match.
In the world of “format” where the proper rules are changed to alternate breaks, and you get behind, it is IMPOSSIBLE to get back into the match if your opponent wins his break games.
