Hi Brett:
Jack is currently engaged in the final stages of preparing the New Instructional Video Tape/DVD and is spending his free time on that project. The new tape will contain a well-rounded discussion of batting mechanics, diagrams, and drills to help explain circular hand path, torque and the other concepts. In the DVD format, the video will have various chapters so that you can quickly review the topic of choice.
In the meantime, review/
study the current Instructional Tape(The Final Arc) and you will see a very clear explanation of bottom (and top) hand torque. (The "Final Arc" Instructional Tape contains a one hour discussion on batting mechanics and it takes time to fully understand all of the content in one viewing, unlike the "See the Ball - Hit the Ball" tapes). Torque is a major factor in producing the mechanics of a great hitter, so your time will be well spend.
In addition, you may find the following sections of the website useful:
Wrist Action or Torque
Mechanics that Generate Bat Speed
In the future, we may create a quick link section of prior discussion board posts so that you can review the important discussions regarding all facets of the swing.
