How can the self-racker in 8 ball manipulate the rack to his advantage?
-making it easier to pocket the 8 ball? I wouldn't know how that's done.
-by not mixing up solids/stripes properly to create easier layouts? maybe
To me there's no problem with rack your own 8 ball. 9 ball, well that's another story and I love to rack my own.
Oh and since it was brought up Magic Rack is a major interferance. It traps balls withing the rack continually, especially in 9 ball. I could not imagine the problems using it in 8 ball on a barbox, balls would be all over it.
