G'day!
The Harold Swash video I have is called "Putting Insights." I haven't actually compared it to "The Art of Championship Putting," but I imagine they are very much alike in content. My video covers the same technique points made in Harold's articles (see the Magazine Rack in my News section or see this article by Swash:
http://puttingzone.com/Gurus/swash.html.) I've met and talked with Harold several times now, and he is a very nice guy.
As far as my book goes, I am hopeful to start circulating a draft in the next month or so to try to find a suitable publisher. Thanks for the interest!
Cheers!
