I agree, winner breaks is the way to go.
When I watch the US Open, I want to see those huge packages.. the bigger, the better.
Hugh packages on the streamed matches at the US Open 9-Ball Championships are fairly rare. The largest over the past 5 Opens were:
2014 -- 4-pack, 2 times in 33 matches
2013 -- 3-pack, 5 times in 34 matches
2012 -- 5-pack, once in 37 matches (by Eckert). Next highest -- 3-pack, 8 times.
2011 -- 6-pack, once in 39 matches (by Klatt, who lost the match to Appleton). Next highest -- 3-pack, 4 times.
2010 -- 6-pack, once in the 20 matches I watched in full. This was the famous Immonen/Klatt match, with a 6-pack Immonen), a 3-pack (Klatt), and a 4-pack (Immonen) in 15 games, interrupted by two dry breaks. Other than that match, the highest was a 3-pack, 6 times.
