Habitually, I think about how to maximize my efforts when using the DYI driving net over the winter. As I was perusing YouTube, I stumbled across a video by Hank Haney; which by the was was posted on Brian Penn’s page. Then I remembered about a post I commented on by Brian Penn dealing with taking 100 practice swings a day. It was fate, so I figured I do more research and this is what I found out.
