I believe that the outcome of this dialogue is that we agree to disagree on some points. I definitely think that anyone that is an enthusiast of any kind should thoroughly research the object of their enthusiasm. This is the only way to learn the answers to all of the Why's, What's and How's. On-line Forums are good, but research should not end there. It should include scientific articles of research, technical reports, books, etc. If you are serious about learning about your particular endeavor. learn what the scientific community has determined along with the experiences of fellow enthusiasts.
