Ben Doyle's tape is the best tape I have seen related to the golf swing. He covers all 24 components, power packages and loading procedures. No other tape comes close in terms of the number of demonstrations swings that are done. He demonstrates the swing from different angles.
The progression he shows works from chipping, punch shot, pitch shots to full swing shots.
The quality of the video image isn't the greatest, but I bought the tape for the information it provides. The tape isn't cheap, but I found the money well spent. There tape will stay in my library permanently.
Each time you watch it, you learn something new.
