My son has taken an interest in bowling. He is mainly a straight bowler, but is trying to develop a hook. Aside from a coach, what are some other ways he can learn to develop his hook...ie books, vids, etc? I am working with him, but I want him to work on some things on his own so he can feel he accomplished something on his own thereby boosting his confidence. Any and all suggestions would be greatly appreciated. Thanks in advance.
