I get sometimes too carried away and can easily take my eyes off the ball.
My worse problem is not keeping my eye on the ball also, it affects everything.

There are two ways discussed for watching the ball strike:

1) track the ball in and stabilize the head/view on the impact area

2) as the ball is coming in at some point, say, for example when the ball is 6-10? feet away from impact, forget the tracking and switch the view, head stabilized, to the area of impact. See D. Knudson tennis book, Biomechanical Principles of Tennis Technique.

I sometimes watch videos or do stop action on my DVR to see which method the pro's are using most often. I have definitely seen pros track as #1. I believe that they will also break off and switch to the impact area but have not viewed enough for stats. I tried viewing as #2 and liked it.

With the backswing, Elliott describes an angle between 1) the line between the shoulders and 2) the line between the hips as a measure of trunk twist. For the back swing he says to have the shoulders go back farther than the hips as a means of loading, stretching the trunk muscles. Elliott does not describe, I think, the arm forward of the body plane as Macci does. But the main idea seems to be - add power from the trunk. They also both start the forward swing with the upper arm up - elbow raised. ( I think that upper-arm-up is recommended because it gets the lat muscle somehow more involved.) Macci does not discuss muscles and Elliott does. Best book that I have found on stroke technique is Technique Development for Tennis Stroke Production by B. Elliott, M. Reid, & M. Crespo. Available only from the ITF Store for $20.
