Hi GSanders,

I use video a little bit, but I'm not a big line drawer. In my opinion, the key is consistency. Try to keep the camera constant with your student from lesson to lesson. If you are comparing to a Tour Swing, make sure you are using angles as close as possible between the two swings.

Michael Breed actually wrote an excellent book on the subject...

I am really looking forward to responses from other teachers as to what they do. I would love to become more skilled in this area.

Sorry I'm not more help, great question!
