BrianM ... I'm impressed with the scope of your teaching philosophy. I must say you have come a long long way from the days on your old forum when I was posting as "Horton" and you were just a total TGM redneck who refused to listen to me or mandrin. How many years ago was that ... 6, 7, 8 ...??!!!!
In order to survive in any technologically-driven occupation, you must learn and evolve ... and that's what you have done to your credit. Meanwhile, I've somewhat regressed with age and have been overtaken by TrackMan and even Jorgensen's D-plane concept.
As you know, I only reappeared on your fine forum recently, after reading some of the mandrin postings. Btw, where is mandrin ... I miss him and still have many of his mathematical analyses bookmarked.
In technical sales, you must know your product and that of your competition ... but you must not spew out all your technical knowledge and risk overwhelming the customer. You just offer enough to get the sale ... and keep the rest in your back pocket. Your approach to teaching golf seems to follow that wise path.
Now if you succeed in reducing your weight, you will be rocking ....
