I was watching Chua in the 2017 Japan 10 ball Championship and noticed his break was very consistent. The 8, 9 and 10 usually ended up by the racking area within 12" of each other (makes an easy last 3 ball run), the 6 & 7 up towards the top corner pockets, the 2 & 3 heading toward the lower corner pockets, the 4 & 5 heading towards the side pockets, 1 usually in the top half with the cue ball in the same half. He always racks 4 & 5 behind the 1, 8-10-9 in line, 6-7 between the 2 & 3. It seems to me, with such a consistent break/setup, the "winner breaks" has a huge advantage in this level of play. I like the US Open 10 ball rules of alternate break. It makes for a more exciting match rather than a shutout or near shutout. If the winner breaks, maybe the loser should rack
