Mo Pinel covers this in his book, "See It, Feel It, Do It" (which I recently purchased and have "devoured" for its content). The section on Focal Point Alignment System covers target, focal point and ball trajectory; basically, proper use of these helps prevent cutting off the shot [not following through] and pulling/tugging the ball inside of your target line. GREAT stuff !!!
I've been working hard in practice since buying and reading this book and I've been more consistant, more confident, and more solid in my approach fundamentals; all deuces the past three weeks of league and rolling about 15 pins above my current average for that time period.
