Assuming you have good key balls for either break balls in position A or B (I'm using the cue balls just for the A and B reference), which do you prefer? Aside from the ability to reach the break shot, are there other considerations for not wanting to choose one over the other? Obviously, I'm getting at the idea of using break balls close to the rack and whether there are any reasons to prefer B over A (again, aside from whether you can reach it or not).
I prefer option b - no matter the playing conditions. It may be easier to see the 90 with option A, however this is where a players personality and or style enters. Either option is reliable but it is not as easy to get stuck in the stack with option B, there are many options as to how to approach either shot ie (cue ball spin.) I guess the real answer is you do not know untill your at the table, but I prefer the break ball to have some distance between it and the stack - if given the option.
