I cannot understand the alternative to learning a feel from mechanics. A feel is a habit that is ingrained from repetitive acts, that is, mechanics.
This is dead on in my opinion. What exactly happens when a student completely new to the game strolls in to take his/her first lesson and has a horrible grip? Practically every instructor is going to place that students hands on the club in a way so that both hands can work more cohesively. The student is then going make swings with the new grip until it feel more natural. I am not saying that you can't play good golf with a bad grip, but virtually any instructor is going to teach someone new to the game a decent hold on the club and then allow the student to get comfortable with the new grip through practice. If that isn't learning feel from mechanics, I don't know what is.
I'm sure there are a lot of TGM based instructors out there that preach in a highly technical way and try to teach the student every term in the book and quote the odd numbered pages from which the terms come from. I don't think this should be confused as teaching "feel from mechanics" which I think occurs on some level in most golf instruction regardless of whether the "mechanics" come from TGM or the worst pop instruction ever. My instructor is very knowledgeable of both TGM and Morad and he has mentioned technical terminology from either discipline exactly zero times. He has no idea that I even know what the book is.
