I had an APA 7 mud rack me twice in our set a few weeks ago. I hit the center consistenly center and solid. It got me thinking about what it takes to do that. I don't have Racking Secrets by Tucker but thought about this the other day. I was talking to someone and he said that all you have to do it put the whites touching on any pair of balls and it will break less strong. (i.e. the white on the stripes or the numbers on the solids) He said that because there was no colored coat on that spot it was softer there and wouldn't break at hard. And the more you get lined up that way the softer it'll break. He was dead serious. I figure him for a retard anyway, but just wanted to hear your thoughts on that.
