how do you know if you controlled anything without balls to control?How are you going to get a repeatable break shot that allows you to (pretend you)control what happens on the break?
No better tool on the market to practice the break shot...
the only thing you control is the CB but you don't know if the spread will move the CB.
Rack and break!
1. you'll learn how to rack, maybe less important with templates
2. you'll learn how to break
3. you'll learn how the balls spread with all games and rack
4. in the era of great video cameras in your phone, getting a tripod and recording yourself breaking and then analyzing it will provide a better learning curve.
5. Practicing the break with a friend will even make it fun
