For the last three months now I've been working on different kinds of breaks in 9-ball and 10-ball. After 1000's of breaks for each game I've come to the conclusion that about a ¼ speed break in 9-ball makes you a wing ball a good % of the time and you have a shot at the 1-ball if it doesn't go in the side. Power breaking in 9-ball is not necessary or even the best choice IMO. You can also rig the rack so the 9-ball goes in the bottom corner or close to the pocket for a combo or carom later in the run. I'm not saying to cheat…I'm just saying.
In 10-ball I found breaking a little better than ¾ speed will get the 2 and 3-ball (corner balls) going 4 rails and back at the foot corners and the 1-ball either goes in the side or back by the corner foot pocket for a shot. To get the 2 and 3-ball not to collide with each other most of the time you have to rig the rack so one corner ball leaves the rack a fraction of a second before the other corner ball. Johnnyt
