I am looking for some good drills to really try and be specific about improving my 9-ball game. I have seen some excerpts from the 1st 3 Bert Kinister videos and thought they might be a good place to start. They are fairly expensive though, and I don't want to make the purchase if they aren't all that great, or if there is something better out there. Also wondering if someone has them but isn't using them and wants to let them go for fairly cheap.
