Gregg said:First off, listen to Bob Jewett before a nitwit like me.
Second, the drill that I feel kept my focus and improved my game over the past few years is a drill found on Burt Kinister's "The Short Game".
Try to runout in rotation, comming off the back rail first;
I will thrown in my agreement for "The Short Game." Keep in mind that the diagram Gregg provided is the simplest form of the drill. There is a lot more to it. Kinister's tapes have caught some flack for not having enough material on them. In some cases this is true. In this case, I think "The short game" is well worth the price. The drill and the harder forms could be covered in about 15 minutes, but the advice Bert gives while the student is working on the drill in the tape is very good. The gist of the drills is learning to use the rails to control shape by getting on the correct side of the ball each time. If you just have the layout and simply try to "get out" each time, you are really missing the point of the drill. As he says on the tape, he is not interested in you making recovery shots with these drills.
In addition, get "The Middle Game" and "The Long Game". Very good series. The last tape in the series "Putting It All Together", can be passed on.
