Full rack rotation takes too long, not good for audiences. Bank pool already exists, there's short rack bank and full rack bank pool.I have been away from the game for two years. Since I have been paying attention again I still find the 9 ball game as being broken. So I have two questions: 1. Why hasn't 15 ball rotation ever been tried as the pro game? 2. With 9 ball why not add a rule where the shooter has to bank every other shot and make the game a scoring game where you get points for the numerical value of each ball?
