Did you read the post right above yours?
Not until after I posted....I see you corrected yourself....good job.
Regarding head ball and second ball break.....I don't think OP is opposed to second ball break and even mentioned he does not need to crush the rack......OP was asking how to get into the center of the table.
Center of the table can be achieved with both head ball and second ball breaks.....I suggest if I have an "option" (assuming I am making a ball) that I would rather the CB be in the center of the table which seems the odds would lean toward more options for the breaker.
In addition....reading the table would determine if I am using a head ball or second ball break.....If I am consistently making 2,3,4 or more balls on a crushed headball.....and can squat the CB on the center of the table....I probably will be using that break.....If balls are constantly going in with a second ball break...probably going to opt for that.....I am not going to "limit" my options by only using 1 break.
Regarding controlling the CB (which is the OP's intent)......A good system of control is to use the light reflection on the head ball (or second ball)....most tables shooting the light reflection square on is a full ball hit (no matter where you break from).....however...you can use specific parts of the rectangle light reflection to not only change the break and "make balls"....but it is a easy consistent aim point and can be used as a "cut break".....
For a second ball hit medium stroke......aiming at the "side" of the light reflection you are breaking from".....use a touch of low right (from the right side) and the CB will go to the side rail and back out to center table.....You can "experiment" with different english, speeds and contact points on the light to get more consistent results.
Even changing just the speed of the break can result in a difference of making balls or not making balls.
Just have fun with it...be find a way to create consistency and adjustability from table to table.
