I do as well.
I'm going to get my kiddo ready for school here soon so I'm going to force myself to be as brief as possible. I'll second what Mike said, too, as that'll save me some typing.
5 Lessons - Great if you want to swing like Hogan thought he swung. Easily misinterpreted.
TGM - Great in 1960. Outdated as hell now. Also not "instruction." Lots of incorrect info and missing pieces.
MORAD - The ultimate in method instruction, except the method is constantly changing with Mac's whims. Too much emphasis on "looks pretty."
Grant's done good things. We've obviously had the pleasure to work very closely with him, and I think he'd say the same for us. What he - and 5 Simple Keys® (you should really look into this) - have done is take a TGM background, to take some MORAD knowledge, and add a whole lot more to evolve and continue to grow. Grant is what I call a fellow "explorer." Explorers are constantly looking for new information.
For example, the whole "center of mass versus center of pressure" talk that's going on in certain Facebook groups among instructors? It's old news to a few of us, and our observations, predictions, and rudimentary experiments were spot on. Grant was highly interested in that information when we shared it with him. That's why we were able to get him on the SwingCatalyst at the PGA Show. That's why he bought a SwingCatalyst of his own. (And heck, 99% of golf instructors still have no idea what we're talking about, and won't ever see this study, work, research, etc.).
Grant's also not beholden to the MORAD way of doing things, in terms of how EVERY swing must look EXACTLY the same. He in fact takes a much more "5SK-like" approach - fix the student's priority, let them do whatever other "personality" type stuff they have in their swings, and just focus on a few key things to improve their golf. It's a system of teaching (prioritizing, that is) that works for everyone from beginners to PGA Tour players. 5 Simple Keys® is heavily based on prioritizing the five things (and yes, even PGA Tour players will have to work on Keys #1 or #2 sometimes).
Anyway, long story short, you've listed an odd mix with TGM, MORAD, and 5 Lessons. A lot of the instructors I respect - a lot of the "explorers" out there - happen to have a TGM and/or MORAD background, but that's largely because they're EXPLORERS. They're constantly seeking knowledge and truth. They're looking in every crevice and mining for whatever gold is available. That means TGM. That means MORAD. That means anything that seems to have some sort of logic or truth to it. So that's often the reason why good instructors have that background - because there's only so much out there.
P.S. The side of instruction - perhaps the MORE IMPORTANT side - is communication, and it's completely lacking from this discussion. It warrants mentioning, though. How you are with people is important. It's why Butch Harmon is still a good instructor, and why he continues to get so many good students on the PGA Tour.
