I have taken a look at several alternatives to TGM the last 9 months or so. Some of the more interesting alternative seem to be heavily influenced by HK. His legacy is secured as far as I can see.

LBG have a TGM cousin over at Advanced Ball Striking, mr John Erickson. He was originally a student of Ben Doyle, and basically was breeded into a swinging TGM pattern. In the middle of his professional carreer, he concluded that the stroke pattern he had grown up with didn't hold up under pressure and converted to what he calls Pivot Driven Hitting. Per description it is quite different from the hitting protocol that is so often discussed here, but apart from a few specialities that he has implemented (such as using clubs with very flat lies) I am not quite sure what the real differences is when we get past the semantics. I think there is a different understanding of the pivot and Accumulator #4. But on the other hand, Lynn Blake's hitting pattern looks very pivot driven as well. It takes a pretty good eye to see the difference when Lynn Blake hits or swings. He has a beautiful pivot motion with both stroke patterns.

Then there is a bunch of Ben Hogan followers. I wouldn't excactly call it a teaching school, because it is probably mostly for the enthusiasts. But nevertheless, there is a very active subforum dedicated to exploring BH's swing over at Golfwrx.com. A lot of very knowledgeable people there too, and some of them also know their TGM.

Then you have MORAD, which is Mac O'Grady's project. I don't know much about the swing, but he was a HK disciple and while he eventually concluded that TGM had serious shortcomings, he still seems to attribute at least 75% of his approach to HK and TGM. What's perhaps more interesting on the big scene is that the current big hit - the Stack & Tilt - was developed from guys that came from MORAD and was heavily influenced by TGM. I am reading the S&T book these days. It is a pretty simple motion, and what they write is very goal oriented and relevant. Everyone who struggles with a slice and with inconsistent ball contact should read it. As I said, heavily influenced by TGM, but the style and purpose is totally different. HK tried to make a general theory of ball striking. These guys have done the opposite; Deliberately emphasizing a stroke pattern and components that (hopefully) cures the slice and produces solid ball contact time and again.

A very different approach that I find very interesting and refreshing - and also very complimentary to TGM is the works of mr Kelvin Myiahira. He is a speed trainer that has become very occupied with golf lately. His work seems to be only moderately influenced by the golfing literature. I can't see that what he teaches is much in conflict with TGM, but he is emphasizing different aspects of the golf stroke. If you wander what happens between the hips and the shoulders you might find spending a couple of hours reading his blog worthwhile.

There are of course a lot of other teaching approaches out there too, but most of them are very hands-on, lacks a systematic approach, leaves a lot to the teacher and can't really be regardet as a school.
