Hi I am fairly new around here. I have been reading a lot of the posts and watching some of the videos (Tom Tomasello) and it seems to be the way forward. I struggle with clubhead throwaway and know that this needs to be fixed for me to improve. My main question is that I have head alot about some practice drills with dowels and would like someone to please explain what these are and how they are performed.

Thanks in advance.
