Tor Lowry's videos on Youtube.
Agree on that, Tor Lowry's videos are simply the best.
The Tor Lowry Version III video recently released will take a player to a new level once those skills are studied and practiced. He calls the series "Secrets Revealed" and that's a good title if you come from the old days like me where you only learned by suffering.
A Lowry video has all the technical accuracy of Dr. Dave but is presented with Tor's pleasant speaking voice and teaching style that builds from the simple to the complex, leading the student from concept to concept in a professional manner.
There also was a professional editing effort made on his vids. They do not have any herky-jerky jumping hither and yon, no incomplete topics like some instructors I could name. He does not forget what he was teaching right in the middle of a lesson like some, not does he talk down to the viewers. Best I can recall, there may not be a single confusing moment in all the Tor Lowry videos, they are all so well done.
All in all, a person who can think and work his way through a rack using the methods Tor Lowry teaches will be a much better player, but it takes time and practice, and can get discouraging as one sees the improvement needed.
Lowry videos are inexpensive. The most recent one, "Secrets Revealed" version III has only recently been uploaded to YouTube. I think most or all of his instructional vids are still be available on his YouTube site.
