I own seven of Nick's DVD. This one is by far the best. This video stresses movement to the ball before it even mentions stroke production. I bought this video after considerable study of Fernando Gonzalez's forehand in slow motion. Suddenly, the idea of early preparation was driven home. All of those hours of having an instructor tell me to "get the racquet back early" coalesced. Although the DVD is on the backhand, it has done more to improve my forehand than any video I have seen. The emphasis on footwork and efficient movement to the ball is outstanding. The distinction between the drop step, the kick step and the short adjustment-steps is superb.
Unfortunately, not all of Bollettieri's DVDs are as good as the Bollistic Backhand. However, the Sonic Serve is unbelievable and the Killer Forehand, while a bit to zany for me, is also pretty good.
