I've got a great idea. How about if you make a ball on the break you have to shoot at that set only. If you only make a solid that you have to shoot at a solid.
This should make the game even and a little more difficult for run outs and forcing you to use more strategy and eight ball skills that are disappearing from this game lately in order to make run outs much easier.
Did you just add an existing apa rule? Although giving you crap here that rule does make the run out a touch more difficult. sometimes you break and you only have a kick or a bank at what you made on the break.
I like the idea just don't like the slop aspect of apa.
