David,
Excellent review. What’s funny is that I believe that if Damian asked each of us to write a review of SDTS, they would all pretty much sound like yours. I would venture to guess that most of us were a bit skeptical when we first heard about Damian and/or his system. But once we saw… oh… about 8 seconds of it, we were all hooked! 
It truly is the simplest, and yet most effective, system I have ever come across in the last 30 years. Period!
