Thank you all for your input. The presentation went off as planned on Friday. I gave an introduction to TGM for about two hours (actually had to cut my outline from 10 to 6 pages ), before fellow A.I. and PGA member David Orr, aka "Annikna Skywalker", discussed Swing Spectrums and Stack and Tilt. While some may have been overloaded with all of the information, the presentations served as an example that there is more out there than conventional instruction can provide; objective information that answers all questions.
On an ironic note, I sat with a fellow PGA member, that I had not met before, at lunch before the presentations. He told me the last time he heard a presentation on TGM was Valentine's Day 1983 at a meeting of the Georgia Section of the PGA; the day Homer Kelley died on stage making his final presentation.
