I will say this that there is a different stroke in playing on a barbox. But, I doubt that it will take very long for a champion to adjust. For instance, in a 10 ahead or so match...I think that a pro or big table champion will easily adjust their stroke. The strategy is still the same with regards to runouts and safety play. I always practice running balls on a big table to improve my accuracy on a barbox. You simply adjust your break and your stroke. That is it.... Yeah if you are using a typical barbox cueball it can also cause you to adjust as well. My point being is that a good or great player will adjust his or her game. The learning curve may be enough to give that "unknown" barbox player an edge in short races and that is about it. I think it is much easier going from a 9-ft table to a barbox rather than taking a barbox player to a 9-fter. I remember playing some players in St. Louis that would give me the last 4 on the table playing 9-ball and either rob me or I would break even if I was shooting well. Trust me....those days are long gone. I do not think ANYONE is going to give me the last 4 anymore.
