I will only add to this thread that my personal best in 8 ball was breaking and running a 4 pack on a diamond 7 footer. I'm not a world beater, so that was a highlight for me. For what it's worth, I've not done that on a 9 footer. Then again, I rarely play 8 ball on 9 footers, preferring 9 or 10 ball or onepocket. As far as I am concerned, 8 ball is best for league play, and I do enjoy barbox 8 ball and always will. IMHO, 8 ball is the only reason bar boxes should exist.
