I have to laugh at target pool and the likes. Put a dime on different places on the table and see if you can get real close to it W/O hitting it. Put a piece of paper down...keep folding it smaller. Almost every drill can be made into a control your CB shot. Speed with shape is a huge part of running racks or balls, but you don't need a bunch of fancy gimmicks to practice/learn it. Johnnyt
